Luma Labs Tiny 1.5 Inch Monitor

Luma Labs makes a tiny monitor called Gadget Display UD7 that connects to your PC or laptop via USB. The tiny 1.5 inch screen won't display much but Lima Labs suggests using it to display the latest tweet from your Twitter followers or the latest update from your friends on Facebook. It can also display a small clock or stock quotes.

See your Twitter and Facebook Feeds Live. As well as your stocks and other Gadgets. Brighten up your home, office, or dorm room with the wonderfully colorful Gadget Display. In addition to Twitter, Facebook and Stocks select from dozens of clocks, CPU/memory meters, and photo displays that easily connect using USB. Accessorize your computer with your selection of bright analog or digital clocks and other wonderful displays. For Windows XP (SP2) and Vista.

The miniscule monitor sells for just $29.95. An image of the monitor on Slashgear shows it barely having room to display a tweet. Slashgear suggests it acts more like a digital photo frame than an actual monitor.
