Original Paper/PDF: http://paradise.caltech.edu/~cook/papers/TwoNeurons.pdf Worth a read, but from an older physics simulation to "present a two-neuron network that can ride a bicycle in a desired direction".

EDIT: Used author's site instead. Thanks random numerical user!

Very nice figure ! The almost perfect symmetry is quite amazing, my eyes like that ! Anyway, I have a question : For your different 800 trajectories, did you slightly change the initial conditions (e.g. velocity, angle of the wheel, ...) to get different results each time ? If so, by how much ? Or did you introduce some statistical noise ?

I'm not a statistics person, but there is something significant in the harmonics of how it falls. A scale would take away from the visual appeal, but are the harmonics related to wheel size, crank ratio, or some other factor?
