Very nice but....
Viery nice but...why do I think someone will try to build one of these and then put it on top of their computer monitor?
On the other hand, at one point in the seventies there were sound visualizers for home stereo. They consited of a shadow box with a translucent plastic cover. The different frequencies of music would light different colored bulbs in the box. IT was WITHOUT A DOUBT the most boring thing I have ever seen in my life.
This is cool if a bit dangerous.
