VCR cassette clock
Although you probably don't have a VCR anymore, you must have a few VHS cassettes laying around somewhere. By using one VHS tape, LED diode and an old quartz clock you can make pretty unusual clock.
What must be taken care of is that the numbering should be anticlockwise since the transparent disc holding the numbers is being rotated from left to right. The numbering of hours is accomplished by etching or engraving the transparent disc so it can catch light from an LED below. Engraving could be done by using hot soldering iron and steady hands.
