micro:bit CubeBit 5x5x5 4-tronix

Magical RGB Cubes of Awesome. Lovingly hand-woven from pure Rainbow by Unicorns (ed: suspicion of hyperbole)
These wonderful cube kits can be assembled in only a few minutes with only a small screwdriver. No soldering is involved.

Every cube is made out of pre-assembled slices that have FireLeds on both sides to give an all-round effect to the lighting.

Learn about co-ordinates in 2D and 3D. Create wonderful visual effects and stunning indicators to sensory events on your Microbit or Raspberry Pi

Use the Cube:Bit base available separately to provide power, connect your controller, or directly plug in a Micro:Bit or Raspberry Pi Zero (Full size Raspberry Pi work fine of course, but don't fit directly without using an extension GPIO cable, or simply 3 female-female jumper cables for 5V, Gnd and GPIO18)

With Raspberry Pi, use any of the WS2812 code already available to drive your Cube:Bit eg. Pimoroni, Adafruit or 4tronix FireLed products.

With Micro:Bit we have written a special Makecode package that "knows" about the shape of all the cubes and can map from x, y, z co-ordinates directly to a pixel anywhere in the cube. Write to a whole plane of pixels at once, create a moving rainbow effect in only a few lines.

The possibilities are endless

Oh, did we mention that you can stack them, so you can make a tower as high as you like!
