This is the second of my two PixelBlaze projects (The first is here)
This one uses a cube platform with a single 8 by 8 LED matrix on the front.
The cube is designed to hold swappable frames with different designs on them.
Each frame consists of a wooden rack style holder with 3 layers of acrylic. The first layer (closest to the lights) is white acrylic, which I use to diffuse things a bit.
The second layer is a thin piece of clear acrylic, which is coated in black spray paint on one side and then engraved with a pattern or image.
The front most layer is the one way mirror acrylic I mentioned in part 1. It serves to hide the design when things are not lit up.
Each of the frames has a small steel rod on the left and right edges. This connects to a pair of magnets in either side of the cube, which holds the frame in place.
Here is a video showing the five frames I currently have in action:
