/*
Instead of doing the brightness using the "strip.setBrightness(Brightness);",
how about setting Red to 150, 0, 0 and Green to 0, 150, 0?
And set the sparkle to 200,200,200.
This way the flash of the sparkle will be brighter than the brightness of the 
rest of the colors on the ring.

Well, that was too bright.  I used lower numbers for the colors in the sketch.
