Call me a huge nerd, but I recently decided it was necessary to memorize the color codes used to designate the values of different resistors. I've also recently become interested in making (relatively) large scale representations of electronic components, either in a semi-functional or purely artistic way.
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!
