Algodoo

Grow any type of material, as long as it's in box form. Not a square polygon though; it has to be a "box".

Keeps the color and/or texture when growing.

Uses custom geometry variables and readable, so algodoo 2.0.1+ only.

Go on, download it. Try it. I think you'll be pleasantly surprised. Have fun, please remember rate and comment (even if you have something mean or criticising to say), and have a nice day!
