I did take a look at Simpull, however the demo application failed to
run as it relied on some library which wasn't supplied or referenced
to - I just got annoyed after spending two days failing to get Phys2D
and JBox2D to work in Android and didn't bother trying to work out the
problems!

I might give it another look though...
