Algodoo

it's a good idea to take the random number from algodoo. i once made a function for a random number using math.mod
btw the random color in algodoo is not truly random. it uses an algorithm to simulate randomness and so does every computer program. if you know the algorithm you can predict the "random" numbers.

Good job! you use the color, that is a simple but good idea

Or you could use rand.uniform01, it also randomizes it. Algodoo uses it to randomize the colour for new objects.
