This is a picture taken from QLeVe3, my Quake 3 level viewer.
For now, this is work in progress, and it has quite a few bugs, such as
"not too curvy beziers" or the "some.textures.are.missing.due.to.not.
reading.shader.scripts" syndrome. Sky isn't that great either...
When I'll finish it, QLeVe3 will be available at http://qlv.iwarp.com.
