[Spikenzie] has created an 8×8 LED array that fits inside an ikea frame. He multiplexed the 64 red LEDs on a PCB with connections on the back. He then used a MAX7129, an LED multiplexer and driver, driven by a PIC over SPI to do animations and play pong. He then encased the array in laser-cut cardboard and white acrylic to get large dots. This entire assembly was then placed inside an Ikea RIBBA picture frame. The result is an aesthetic homebrew display that is easy to control.
