When I tried the code above, I got a number of error messages which I suspect is because Nicholas was probably using a beta test version of MicroPython. So, I modified his code to compile without errors, and I modified it to run on the Proto-PIC "Micro:Pixel", a 4x8 Neopixel display add-on board for the BBC Micro:bit. The only change to make it run on the Micro:Pixel board was to change the number of neopixels from 30 to 32. The other change was to make a cut and jump on the Micro:Bit board to use Microbit pin8 instead of pin0 to drive the string of NeoPixels. The Proto-PIC website has a note on how to do this on their page that describes the Micro:Pixel board. Below is the code listing (an image file):
