Kick-Off! [Babel]. $194.00 ish.

An automated computer crash monitor and restart gizmo. Plug your power cable into the dongle, the dongle into your USB port, and pop off for a cup of tea or something. If the gadget doesn’t sense any activity on the PC for a user specified time (e.g. 5 minutes), or it senses that an application has crashed, it will try to restart the machine automagically. Great for web servers and the like, eh?
