The original Sierpinski pyramid print design by ricktu is here: Fractal Pyramid with Continuous Cross-section
Then Chaz493 thought of turning into a lamp using transparent filament and a base here: Fractal Pyramid Lamp and Base
After I printed the base and pyramid I thought of lighting it up by inserting a couple of CPX's (Circuit Playground Express) coded for light patterns in the base cavity. This worked a treat.
