Hyperdyne and I made one a long time ago back in 99. We got the triangle leds from Mouser. This was before Chen. I have schematics still, but it's for a plasmablde. I'm sure Hyperdyne could draw one up quickly if you describe what you'd like the LEDs to do. We didn't even have to make the custom LEDs like Chen. Digikey sold triangle LEDs that were the correct size and everything.

Digi-Key has a minimum order of 10 per LED, and then some shipping and handling charges.
If anyone makes an order, I would be in for 2 of each color.
