[Retrobrad's] spinning POV display has long been our favorite. When it popped up on our radar again this morning we were surprise to see we never ran a feature on it! But now there’s so much more to share. Hit the projects icon at the top of his page and you’ll not only get the 8×85 RGB display’s build instructions, but he’s also built a 32×64 pixel spinning display.
Even if you’re not going to make one of these, he explains some pixel-graphics techniques that are useful in other instances. Check out his video on using spreadsheets for creating the hex arrays necessary for each frame the 8×85 display. It’s embedded after the break along with demos of the two displays.
