This is pretty good. ClickWell for those who've never seen it, this is a good example of how the endless tape loop works in an answering machine, tape announcer or continuous music tape player. It also demonstrates a basic principle which was the basis of the spiral escalator albeit rearranged as a double helix with inner and outer tracks transposed at top and bottom to create both up and down 'lifts'. |
