Might be neat to add this to an actual car PC…This custom mod gives your computer the personality of KITT, the computerized car from Knight Rider TV fame. It slides into a CD drive bay, and only has a single standard power connector. The project is a light display which imitates the dot in KITT’s hood. It looks like the scanning eye of the car’s computer that is so smart it has a personality and acts autonomously. Some people have said the computer shows more emotion and personality than the main actor, David Hasselhoff. Link.
