Send messages across the room with this LED pen, which gives you 118 characters to make your point. Its brightness is controllable, and you can speed up its scrolling or slow it down for those slow readers.
There's something about scrolling LED text that attracts an unbelievable amount of attention. Some of us wore LED scrolling buttons as promotional devices at a trade show last year, and people were constantly asking us about them. Sure beats smoke signals. It's $29.95.
