Echo Nest hero
When I'm not blogging about hacking online polls - I spend my time at The Echo Nest where I get to do some really cool things with music. Over the weekend, I wrote a program that uses the Echo Nest API to extract musical features to build the core of a guitar-hero like game. Even though this is a quick and dirty program, it performs quite well. Here 's a video of it in action.

Hopefully I'll get a few programming cycles over the next couple of weeks to turn this into a real game where you can play Echo Nest hero with your own tracks on your computer. Of course, I'll post all the code too so you can follow along and build your own computer game synchronized to music.
