In the 1980s, executive desk toys were a super-hip phenomenon. If you had a desk, you had to have Newton's cradle, or perhaps Pin Art. But digging deeper into the desk toy world, you'll find oddball items like the Seiko Executive Egg. It's a plastic egg mashed up with a voice recorder. But because it's from the early 1980s, it records the voice using a tape recorder head on a magnetic disc, much like those used in floppy diskettes.

Tune in to this video for a thorough investigation of the egg and its guts—including a repair job.
