We've been selling our LED matrices for a while now. They have been used in some cool projects, including our very own LED coffee table. The matrix is sold in dual color (small and medium) and tri-color (large). Fortunately, our version of the matrix is Keanu-free.
By now you're wondering, "Hey there buddy! What's your point?" My point is the above picture - a rad project from SparkFun customer John Peterson. You may have seen John at Maker Faire at some point and his Puzzlemation Project is incredibly cool. The picture doesn't do it justice - to see the project in all its glory, check out the video below.
Awe-some. Here's how John describes his project:
"Every time we look at computer screen, millions of pixels of light disappear into our work, our correspondence, or our entertainment. Imagine if you could capture those dots of light and scoop them up as you would grains of sand on the beach. Puzzlemation explores this idea, by dividing the digital display into pixels you're free to pick up and re-arrange. It can be used to create things as diverse as modular animated signs, to a uniquely challenging dynamic puzzle. It is a tool that lets you create animated light displays of any size and shape for whatever applications you can dream up."
