Arrrrgh. Another thing I forgot about.

Well, we want as much control as possible over this demo in the future
anyway so why not just make the textures for this separately?

Nothing except by drawing pieces?

The band-like textures look very interesting and difficult to 
understand when sliding... I'm not sure if this effect will really 
*help* understanding them that much ;) ;)

Hope the audience will believe it when I tell them that yes, it *IS*
just a combination of the two...
