creatures avoiding planks

Update: This post has been translated to Japanese and Chinese. Recently I came across a video of a simulation that demonstrates the use of evolutionary techniques to train agents to avoid moving obstacles. The methodology used seems to employ a variation of the NEAT algorithm used to evolve the topology of neural networks so that it can perform certain tasks correctly. It was written to be used in the Unity 5 game engine to be incorporated to general game AIs which interested me. The results are really cool and the dynamics seemed quite elegant, so I wanted to try to implement a similar demo in javascript that can run inside a browser session.
