Here is the video on thatPoundland lightbox which I modified to show
various colourful animations.

I replaced the cheap LED strip in a Poundland (£2) illuminated write-on
sign (i.e. a dry-wipe marker light box) with a WS2812 strip, added an
ATTiny85 microcontroller, and a TSOP2438 infrared sensor so that the colour
animations can be controlled via a remote. The circuit was initially
prototyped using the Adafruit 16 neopixel ring and the animations are based
on the Adafruit strandtest program.
