Save this file to the Pico board's internal storage L: drive and run the following commands:

L:/>display-ws2812 setup {din:2 straight:60} brightness:.1
L:/>draw image-load:hue-32-horz.png
L:/>draw image {size:32,1 repeat-x}
L:/>draw repeat { image {offset-shift:1,0} sleep:100 }

When you run offset-shift:1,0, the display area shifts to the right, making the hue appear to flow.
