Ironic Sans has a really cool idea for a sundial-type clock.

Now that I’ve seen it, I’m pondering ways to (inexpensively) build one. Unfortunately, I’m not much good with designing mechanical mechanisms like this. Gear rings? Layered platforms with capstan type rollers? While a slip-ring would be ideal for getting power to the lamps (LEDs, whatever), using a pair of wipers for each might be easier and less expensive.

I’m open to ideas…
