Addressable Net Test Wall of Awesomeness

@Scheeeeer , Yes, but the trick is getting the data back up to the next strand. You could use output expanders for every 8 strands, up to 64 strands. Similar to the 8x8x8 cube here. The bullet style LEDs like that end up pointing in random directions. I made a 3D printed cap that clipped them pointing downward along the wire which helped.

The LED net mentioned above has a return data line built in so its all 1 string and can be used without an expander (unless you combine 2, as @zranger1 has). It also has the LEDs flush with the string so they aren’t poking out in random directions.
