I always wanted to build a music visualizer, but it always seemed awfully complicated. After finding a sound detector module on the interwebs I thought that it might be doable after all. Using some basic electronics, and a jar from ikea, this turned out pretty cool, and I am quite happy with it. Being a computer scientist student I loved playing with the code, and tweaking different parameters to produce different results. I have uploaded it so you can see what I did, and to use it or modify it if you want. It’s not finished (probably never will be), and not perfect. Contributions appreciated!
