Adafruit's Digital Addressable LED Strips are quite versatile - they're flexible, capable of displaying 2 million colors per pixel, and their LEDs can be controlled individually - allowing for countless project possibilities. 

In this tutorial, we've inserted the strips into a clear plastic tube to create a thin column of LED lights, and then connect them to JavaScript GUI sliders through Spacebrew.

The LED tube could be used as one "bar" of a digitally controlled bar graph installation, as part of a sculptural feature, or - my favorite - a makeshift light saber. Follow the steps below to make your own!
