In honor of burning man 2015, here is an amazing open source LED pyramid light for your IoT (Internet of Things). Projects a holographic-like display of dancing light with the pyramid lens. Features a base suitable to house an 8x8 neopixel grid, a flat diffuser, and a pyramid shaped lens. Many amazing effects can be achieved by sequencing the LED grid and experimenting with various diffuser combinations.
