I fear that this app could be using OpenGL. It's almost guaranteed. It also uses OpenCL. But I'll have a look at the source.

Ok, it is OpenGL in it. But it's SDL. I'll see how it goes when I try to compile it for Maemo.

I see another problem as well... This is heavily based upon physics. Small-scale physics. Calculations per particle.
Do not expect this to run well if it runs at all.

I doubt it will run. It uses SSE3, which is a hardware feature.
