I thought swansont, Klaynos and others would enjoy it.

I'd not actually noticed that...

Yes and no.

 

Cute. But geek pedantry gets in the way. If you can see laser beams from the side, your air isn't being filtered well enough.

Yes and no.

I resisted the erge to say something like that!

Having gone to Laser Floyd many times, I can certainly attest to the problem of visible laser beams being thoroughly solved with fog machines.

Pink lasers, one would presume.

No, the elephants were pink. The lasers were green.

Do you mean "invisible" laser beams being solved with fog machines? If the beams were visible it would seem an air filter would have been a better solution than a fog machine.

Google have cool logos on holidays

when I was a little younger I would save them into a folder because I was bored...

I had quite a lot...

They were original though

Perhaps "making laser beams visible" is a better phraseology.

 

That said, laser Floyd rules, and laser beams rock a billion times more when they're visible.

It's not a good thing to have your beams visible though, it's really bad!

Why's that?

You lose intensity, and collimation in the beam if there's allot of scattering events.

But you might want scattering events when they're used for a light show or something similar so sometimes visible is a good thing....

But yeah light shows... That's why you want cloudy nights....
