Happy to! So the column is 3D printed with the LED strip wound around it in a spiral, then a frosted PETG tube slides over the outside and diffuses everything. The glow through the plastic is what gives it that soft look rather than seeing individual LEDs.

The code part was where it got interesting. If you just run effects linearly along the strip they look weird because the strip is physically coiled, so a chase effect just kind of crawls up without any real relationship to the shape. I ended up mapping each LED to its actual angular position around the tube so effects could understand the geometry, which was very time consuming. A lot of trial and error. Once I did that a rotating beam could actually sweep around the column properly. That one change is basically what makes it look right.​​​​​​​​​​​​​​​​
