I learned how to rotate a cube, see http://eab.abime.net/showthread.php?t=83982. Filling the sides is more complex though. http://eab.abime.net/showthread.php?t=45668 has a lot of good information.

Yes, you can certainly run Devpac from disk on a A500, but there are a couple of things to watch out for. The latest version of Devpac (3.18) requires AmigaOS 2.x+ so if your A500 is 1.2/1.3 then you...
