I can describe it.
It's a 2D realtime physics simulator that allows you to construct various dynamic structures out of springs.
You can drive some of these springs off of a set sine wave, at phase delays and amplitudes you set yourself. Or you can load one of the preset models and let your mind drift as you stare at the anthropomorphic representations of walking and swimming.
Very cool. The amoeba simulation works in much the same way as a real amoeba.
