Ah that's a pity Rick. Could have been a very good capabilities demo - can still be, actually.
Given the time I'd be able to create the volcanic terrain, textures with normal mapping, sounds, particles/ smoke and lighting effects myself, but shaders is a different expertise altogether, which I haven't dived in deep enough yet but from which lava/magma could greatly benefit.
Ah well, who knows if you guys don't then in the future I just might for good fun and completeness, but could be a great part of an AppGameKit 3D tutorial for beginners too.
