That just blew me away! I didn't think I was going to hear anything, but yeah, immediately it gave an almost pulse-width modulated high pitch tone. I'm not surprised, but it is also awesome. I'm so many years old yet I can still hear the hum from CRT's, but I'd say that tone is much higher frequency.

Yeah, this is absolutely WILD. You can definitely hear it... wow.

Heed the warning on that first link. The pattern can really hurt your eyes.
