Red leds?  Guys, I'm 36.  I was eight years old in 1976.  To get LEDs back then, I would've had to break open one of those $35 calculators.  God I'm so old.  My friends little girls have no memory of a time when there were no blue LEDs -- I still think they're the coolest thing ever.

You know, one of
