Circular displays are here! Round screens aren’t exactly useful for productivity, but are too cool to pass buy. Today I’m breaking down a few common varieties to show you how easy it is to get them running with an Arduino, Raspberry Pi, and a regular PC running Windows. All of the displays I've found are linked below.
