The PushPin Light
The PushPin Light serves not only as a desktop lamp, but also as a message board which you can pin your memos and reminders to. You turn the light on and off by pushing the pin unit down, and you can get it for $50 from Design Town. Or you can be like me and build your own. And by build your own I mean stick push pins into a light bulb. It doesn't exactly function, but it does ruin a perfectly good light bulb.
