I'm not really suggesting that this replace the 2d versions, but seriously, try this new version. It's fun.
Sand3d 0.35
Changes:
+/- change the pen size
liquids act like liquid
eraser (useful for building things out of glass)
text (so you can know what sand you've selected)
cursor stack (so you can see where things will fall)
oil take longer to burn out (so you can make rivers of flowing fire)
This version is fun, I played forever just making fountains and stream out of glass and running of water through them, or making a big water tank out of glass, filling it, then using the eraser to poke a whole and watching the water flow out.
You can also do it with oil . . . which also works for burning oil . . . >:)
Anyways, enjoy guys,
and like usual, post or send me your questions, comments, queries and bugs.
