Should mention that I wasn't extremely happy with the result, although it's still kinda neat. The fibers in the tape kind of hang off the edge (perhaps a sharper knife would help with that), and the whole thing is rather sticky, since the edges start peeling up a little. Perhaps something like gaffer's tape would work better. Not sure I'll get around to posting a full how-to, but the idea is that I took 1 or 1.25" square dowel and cut it into 8 cubes with a hand saw & miter box (table saw with a fence would give more consistent cuts though). Taping involved putting down a piece of tape sticky-side-up, setting down the cubes adjacent to each other, and then cutting off the excess with an x-acto knife. You should be able to follow a video of one of these to get the joints and proper colors figured out.
