Coding Challenge: Neural Network Visualization

Neural Networks loosly follow how the brain works. Current Visualizations are kinda boring and bleh. The link below is a basic example.

I am teaching myself machine-learning but can't help but imagine how cool it would be to have something that visualizes it happening in real time. Making the neural network look like its "thinking" would be fun to make. Instead of it being 2d and linear like the photo above, this visualization would have the nodes spread out in 3d mimicking that of a circle or a "brain". As the neural network "thinks" its nodes would activate and light up.

Sort of like this https://youtu.be/3JQ3hYko51Y?t=2m3s . Obviously that requires a lot of processing power so maybe a toned down version of it that can handle it in realtime?

I just found out about the processing 3 software and your videos and they are very cool and informative! So I will be learning how to do this in the meantime as I have to teach myself Java, but I thought maybe that's something you might want to tackle just using random data.
