Bars And Tones Make Pretty Sounds And Visuals

For those of you old enough to remember what a test pattern is, I hope you'll enjoy this as much as I did. 

 

It starts with your standard test beeping, but five seconds in it becomes something else entirely.  It becomes a thing of beauty.  I would absolutely love to see some TV station be cool enough to use this some day.

 

I'm going to have this stuck in my head all day now, and that makes me happy.
