Well, I didn't think the existance of the colors was new. When I was in
high school 10 years ago blue was cheap enough for my chem teacher to
have one.

The news for the trib is "Why are stoplights around the area suddenly
burning holes in my retenas and making me see spots" - which is what
happens. Yes, stoplights can be _too_ bright. If you're coming to MN,
bring some sunglasses for night driving.

IANAP (I am not a physicist) but wouldn't that be really hard to do? But
they make full color RGB-LED powered billboards and things in a
non-blinding setting.

And yes, I took the O2 apart to see how that worked too ;)
