Author here, happy to answer any questions!

Have you thought about ways to make the lights detachable so you can wash the garment? Or is the trade off at a point where redoing it is easier overall?
scottbez1•3h ago
It’s maybe plausible to gently wash it with the filaments still attached? I did actually use connectors so the shirt could be detached from the drive electronics, though I’d be a bit worried whether the stitches would survive and corrosion on the solder joints. Adhesive/waterproof heat shrink could maybe help?

The other option is maybe attach the filaments to an embroidery style patch instead of the shirt itself and then attach it with Velcro to the shirt?

The pwm animation/flicker/ramp up was a REALLY nice touch

Reminds me of a Japanese tech demo on YouTube I can't find right now, of projecting a flexible hologram on to a t-shirt with invisible markers.
