A tool for the security conscious or those that like to annoy passers-by, the Halcyonics Caveo is a PC Card with a built-in 110dB alarm that uses its motion sensor to set up a perimeter (of variable radius, I'd hope) around a laptop. In addition, the Caveo has a special software package designed to lock-down not only the operating system, but the data of equipped laptops, making the theft of your computer not only painful, but hopefully fruitless for the thief.

Most intriguing is the 'Motion Password,' where by using a "series of physical movements," a person may disable the alarm. We're fairly certain one of those movements involves a hammer.
