Okay, here's the new design. Nothing revolutionary. Pretty much like Brian's, but things are moved around a bit and connected somewhat differently to keep everyone happy . One nice thing is that the corner is trimmed for more clearance around the display nipple.

It's fairly obvious that the size of the LEDs do not allow for additional LEDs to be added. I scoured various catalogs and couldn't find any smaller than these, so 4 it is.
