Very cool, thoughtful, and unique gift. Gifter read me perfectly -- I LOVE little scientific-y gadget toys. The toy consists of 4 neodymium magnets and a piece of pyrolytic graphite that hovers ~0.8mm over the magnets. It stows away nicely in a little wood box and will oscillate briefly if you touch the graphite.

Also the gifter gave me handmade calligraphy of a nice message as well as dark chocolate from his country (Germany).
