A wall clock seemed a perfect fit to learn colors - it's something you might look at a number of times per day, it has roughly the right number of digits/colors, and it's generally useful anyway. So I set out designing and after cycling through a couple other designs, I settled on using acrylic parts - beige for the resistor cores, gray for the inner and outer "wires" - glued together with electrical tape wrapped around. It's certainly possible to make it into one big piece of acrylic and painting the cores, but this seemed like more of a challenge and a bit more fun. The clock is 10" in diameter, a good medium sized clock.
Now there's a great new way to learn the color codes and eliminate the need for a google search every time I'm working with resistors!
