Image Description, by Robin Håkanson

Here are som screenshots from my TI-82 demo IMATION released during Dreamhack00. It has som nice parts, faked grayscale (LCD screen's has low refresh rate ;) ), tunnels and other stuff that you normaly find in standard PC demos. For all you pepople out there that have you own TI-82 calculator you can download the demo from You will need CRash to run it (if you don't already have it you can find it somewhere on There is also an MPG version of the demo for all you poor fellows that don't have an as kicking TI-82 calculator, it's lokated on If anyone is intrested in coding TI-82 and Z80 processors i have wrote some artikels about it on (it's pretty good if you know swedish because the artikels seamse to be written in that wierd language ;) ). /Robin Håkanson

Well, thats for sure the most amazing image i've ever seen! Good work!

Wow. I'm totally impressed. That's awesome TI artwork there. Keep it up :)

Well, i guess this would save some time :

Well, sure. Shots always get nice comments and code snippets always get negative comments. Positive comments are (at least one of) the reason people post these shots =)

Yet you have to admit that's pretty nice work with a calculator.


December 20, 2000, 03:46 AM

Hehe, an old girlfriend coded a multiplayer (link-cable) chess on the TI-82 but this one beats her application by lightyears :)

Man tackar för artiklarna

I'm wondering why you guys (the two ones above me) even post that!
And I am curious about one thing - are there bots in flipcode forum, because it's impossible for normal human to write "Wow, good work!", "Never seen that before, even when get drunk!", "The coolest thing I saw here, when you'll start the movie.." and crap of that kind....
Sorry, but it'll be good to eb more realistic... I think... because when some guy post a shit here and somebody says how good is it - it surely won't help the guy to understand the real value of his work!

That above is nice (art), but grayscale and low-pixelation sux a lot, a that's why this IOTD simply sux - I don't care about the LCD, low refresh rate and all other drugs...


December 20, 2000, 03:52 AM

well, after i saw this image, i was looking on ebay to get a ti-82 :)
hope that says it all. i like it!

don't take this joke too serious.
i never saw a really negative comment here, that's why i did that.
unfortunately, the checkboxes aren't visible in netscape :(

"That above is nice (art), but grayscale and low-pixelation sux a lot, a that's why this IOTD simply sux - I don't care about the LCD, low refresh rate and all other drugs..."

Go spew your bile somewhere else. Recognize what the image represents, not that it's not the prettiest thing in the world. Of course, this requires intelligence, so I wouldn't want to put you out ...


December 20, 2000, 03:53 AM

one word : moron.


December 20, 2000, 04:06 AM

Those are the best grapbics I've ever seen on a Ti-82!! I have a Ti-83 my own, and all i've ever made was a worm walking over the screen ;).
BTW, what is that Dreamhack? A contest for the Ti-82?? Is there also one for the Ti-83 ??


December 20, 2000, 04:09 AM

Wow.. If you can't tell that this is a great IOTD then you don't know what you are talking about. To me the IOTD is not about showing great graphics all the time (eventhough that can be nice), it's about showing something cool that you have coded, and this fits that PERFECTLY!
Maybe I should submit some screenshots of the C64 demo I have been working on now and then, just to annoy those who can't appreciate low-res effects! :)


December 20, 2000, 04:17 AM

Het there Robin. Saw that demo LIVE and i must say that it was even cooler than the hw accelerated demos!!! :)

Someone should ban you from this site cuz i cant understand how anyone could say that. Maybe youre a kid thats never seen anything else in your life but hardware 3d accelerated demos/games and dont care about how things used to look if its not super realistic.

This demo pushes the limits of what that little calculator can accomplish and ive never seen anything like it.


December 20, 2000, 04:22 AM

Het should be Hey in my post above :)

If this demo sux... then tell me why it got screaming n standing applauses which NONE of the other demos didnt get??


December 20, 2000, 04:31 AM

Adding my support to that sentiment. I have a TI-82 and can't believe he pulled that off on one of these archaic beasts.


December 20, 2000, 04:36 AM


I agree completely with most of the other posters, but I couldn't resist writing something too:
1. This IS cool. Of course it is. It's about reaching the limits of hardware, and going beyond. On a TI-82 that's doing greyscales on a mono device, on a GeForce that's... Ehm... Well, something that I haven't yet seen. And that's what makes this image at least as interesting as HW T&L 3D shots.
2. Gathering some positive feedback by posting an IOTD is NOT a bad thing. Everyone needs some compliments (well, I know I do). That shouldn't be the sole reason for posting an image, but hey, it's a very nice side effect.
3. IOTD's can help you find other coders. I posted an IOTD for an even more obscure device (Philips Nino), and I received:
* Lemmings art
* Couple of coders
* Optimized version of my own code
So it was certainly worth it. :)

I don't own a TI-82, and I doubt that it will run on the TI-82 EMULATOR that I have for my Philips Nino :), so I'll check the mpg. Keep up the good work!

- Jacco.


December 20, 2000, 04:53 AM

I never said that THIS demo sux, because this isn't a demo - this is IOTD, don't you think?...
Happy coding...


December 20, 2000, 05:09 AM

Haha, såg just att 'Noice' syns i en av bilderna (antar att det är en greetings-part). Trevligt! :)

(Sdw -> Shadow/Noice)

December 20, 2000, 05:10 AM

Now I am pretty sure most of the posters want to kill me, but please let's don't make a stupid flame war here!
One word: please.
All you are right of course and I agree with the opinion that IOTD is a good think and help the developer in many ways - but very often the posts are not much realistic... maybe they shouldn't.
I yes, I am a little kid with GeForce playing UT and sometimes prerendered MAX scenes too....
It is good to fight the bare metal to make something unseen before on it, I personaly myself has such kind of experience with the XT series once...
About banning: if you ban someone for saying THAT... well, then you guys have a problem - One word: freedom!
And notice the posts against the stupid messages here - they are 2 (or 2.5 maybe)... I'm not alone.
Sorry I was only partially right/wrong.
One word: bye.


December 20, 2000, 05:16 AM

k, maybe "ban" wasnt the right word, but watch ya tounge next time
kiddo ;)


December 20, 2000, 05:23 AM

more than one word :

you have of course the right to post your opinion, either good or bad. but you should try to keep it constructive. nobody cares about your antipathy against lc displays.

i think this is the best iotd from the last weeks, or even months. it's something different from the usual "this is an early shot of my upcoming 3d engine..." stuff.

I think this demo is amazing. I grew up using a C64, as I couldn't afford anything better.

I saw a lot of things in C64 demos that pushed the machine a lot (real-time ray-tracing and the likes), and for someone to turn round and say that it sucks because it's not realistic really bugs.

Guys who do the supposedly impossible are how many advances in game technology come about.

I don't want to start a "Carmack is/isn't god" flame war, but I think Zemedelec should look for some articles on the research that John Carmack did for the Quake engine. After all, most modern game engines are influenced by it.

Okay, that's my two pence.

I won't even try to post my site's URL here. This TI-82 demo is way cooler than my OpenGL effort.


December 20, 2000, 07:06 AM

This IOTD makes a statement, and I like it.
I won't go too deep into the younger-ppl-that-grew-up-with-a-21inch-16.7x1.000.000-color-monitor-with128mb-3dgraphics-card-discussion, but I say this:

Maybe 90% of y'all dislike the graphics(hope not), but 100% should respect it.

December 20, 2000, 07:39 AM

Pretty cool !!!
It's very nice to see demos running on calculators.
Now I think that I'm going to try something with my Casio :)

God Jul Gud! ;)


December 20, 2000, 07:59 AM

Tank you man for advice, I really appreciate your efford to open my eyes, but...
I lived in a city/country where the technology came very lately (long live the communism) - and I got the Q source on one competition and still can't believe how that happens... and then (lacking Internet) I spend 2 (two) years reading this C source and trying to oversee the technology behind it... It is pain, you know there is something simple behind all that stuff, but C is not the right way to describe ideas, so I realize the BSP-s all by myself one day, almost understand the perspective texture mapping, all the entities stuff, colission detection - you have no idea how many times I have preread some sources...
And pls, stop that stupid messages about young kids with GeForce-s - they surely don't come here!
And I think that every coder must pass through the test of the slow machine with almost no memory, no HDD and a monohrome monitor - and after all that to love it! I do.


December 20, 2000, 08:19 AM

I have no words for this shot.


I didn't knew that it's possible to do that on a calculator! :P

btw. This is more original than all those 3D shots :)


December 20, 2000, 08:50 AM

Nice work! I like the fake greyscale, heh...

You guys don't have to beleive me, but I managed to pull a blue line on my TI-83. Since the TI-83 has only a black and white screen... thats pretty impressive... I just haven't said anything cause I think that I might be killing my TI-83...

James Matthews

December 20, 2000, 08:51 AM

Hey, that's really impressive. Something like that would have to be written in assembly language most likely, which is a real bitch on the calculators. Especially the ones that TI doesn't officially support ASM on - like the 82. Developing for the 83+ (and now the 89/92+) is really easy since TI have a bunch of tutorials (written by me! :) but more importantly an excellent simulator and debugger.

But to get that kinda stuff from an old 82 is bloody brilliant (Yeah, I'm British)...getting grayscale is always hard to achieve. I actually don't know how he took the screenshots - must have been on Crash, right?

ANYWAY, that's really cool :)

James Matthews

December 20, 2000, 08:53 AM

Yeah, that's a fairly old trick you can pull with the 83/83+. I think someone has claimed red too, but I've never managed to duplicate it. The blue I have...

You know, you have also send a certain byte to the LCD port (can't remember what) and the LCD will wrap around the top. As in, it will display from the middle, but wrap to the top once it hits the bottom:
