I've had these 15mm bubble rods from Kitronik for quite a long time, I thought they would look good when side lit. I used a single neopixel on each end of the rod and illuminated both ends with the same colour. The colours slowly fade on/off and at different frequencies. 22mm copper pipe fittings make perfect end caps and the the laser cut adaptors to go between the two.
