Illuminated PC cables
Computer cables that light up when you touch them or press a button on them to aid in you tracing where the cable is plugged in. Also, the cables could change brightness or flash based on what type of data is passing through them, or direction of data. Data centers where there are tens of thousands of cables could really benefit greatly.
Reward: I wouldnt mind having a few of the products. I would like a reference in the documentation for attributing me as helping with the concept.
