Using Vectors

Here is my second week assignment for Nature of Code. It basically is a system where each Moo changes its location according to the Moos that it is comparing. Also the Moos changing color according to their distance, so when they get closer they transform into this greenish color which you can see if you look closely. It looks like kind of Flies buzzing around. There is still too much to improve on the code, I started to make it in 3d actually, but box() object gave me hard time.
