I'm surprised there wasn't a Google Doodle about him today.

And yet not so young that you fail to appreciate the warm glow of the 866 or 872!  Especially when they twinkle with modulation.  The world's earliest (monochrome) color organ!

Therefore this arrangement - the best solution already built and working. Got some real PIV there along with the pulsating blue&UV glowz.
