A while back I saw a video on youtube where this guy built a nitrogen laser, and then used that to make highlighter ink lase with a greenish yellow beam :) It was totally ghetto, but it turned out really awesome.

This is the beam on the floor (time lapse)

And this is just the floor glowing (I pressed the host to the tile, you can see a little laser light leakage but the letters are the floor glowing not the laser)

Just a few years ago $100 for a 5mW green was a good deal, if you could find it. Now they practically give 5mW ones away with cereal, and everybody and his uncle Bob has one at 100mW+. There might not have been a revolution in technology, but certainly there has been in accessibility.

i paid close to that for a red laser 15 or so yrs ago.
