Theodore Johnson has created an interesting clock that uses edge lit plexiglass tiles. It would take some time to be able to read the characters since Theodore decided to use Eldar Futhark runes as his numbers. Probably no harder to read than an LED binary clock though. This is not the first clock he has built, actually this is just one in a long line of other neat clocks!

“I could create the scratches using a straight edge and a scratch awl. The next problem is what to engrave. Even the thin scratches tend to obscure the figures behind them, suggesting that I would have better luck if I created numerals from segments. Further, the segments should be straight, not curved. I could create a seven segment display, but that would be boring. Instead, I decided to use Eldar Futhark runes, using the first letter, Fe, for one, and so on to the ninth letter Hagall for nine. To be traditional, I represent a zero with a blank. With a little creative overlapping, I managed to represent these nine letters with only nine non-overlapping straight segments.”
