This is an amazing project. Something that could easily be used at festivals or super-clubs. It’s a giant sphere using 100’s of LEDs to create patterns that bounce around in time to music. You can read more about it over at the hackaday website.
I am the the founder and editor of Codeduino. I'm a developer by trade, and a maker by night. I've been 'making' ever since being introduced to Arduino at university - my final year project was an Ableton Live controller based on Arduino.
