Timewaster!

Falling Sand is fun, but I'd recommend Powder Game, which is quite similar. It's as fun as it is to play as it is to read the mis-translated description of it.

Burning Sand is the most complete and most fun of the clones. No one knows who authored the original, which is kinda sad. I wrote a clone in Java some time back. It's slow, though... but does include a range of elements. I plan to go back to it sometime, writing better code and implementing such things as wind (using a low-resolution lattice of vectors, rather than the air pressure system Powder Game uses, which I can't get my head round), moving parts, and weight (so that a big pile of sand can collapse a special "weak" wall). The biggest flaw with AshleySand (...) is that sand floats on water. Retarded, I know. Oh, and no I never released it.
