I took this picture...from the internet. I just think it's neat.

Reminds me of an experiment my dad worked on a while ago. He was doing something that required redshifting lasers or maybe blueshifting. I don't really remember the details, but it involved going to a very high end stereo shop and buying one of their most expensive woofers. But he only needed one, and they refused to sell him just one speaker, because it was a stereo store and they sold speakers in pairs.

He got the speaker back to the lab, and epoxied a mirror to the cone. Then when he shined a laser at the mirror, he could use some tone generator to run a specific signal through the speaker to get the laser to shift its wavelength or something like that.

It seems like a pretty neat solution to me. And also a travesty that he destroyed this really expensive high end set of woofers.

<cynical> Did they really get that wonderful distribution, or is it shopped? </cynical>

What is it, Dippin' Dots on a popcorn popper? :confused:

Sprinkles on a speaker turned face up.

OH duh! Hence the speaker story. :blush:

There's always some shopping involved these days, but that can be easily achieved with a strobe. The flash duration can be as short a 1/100,000 of a second freezing most moving objects.

They probably then started fussing with individual sprinkles to fill in any empty spots.

Lots of (imaginary ?) circle patterns among the spreckles.
My brain starts looking for words.

Tesla motors is opening a location a block from my office. They are having some press event today to celebrate the grand opening, and give rides to the press. Almost as an aside, they have the Dragon capsule by SpaceX. This is the first commercial spacecraft to go into orbit and return safely. Happened just two months ago. This isn't some musty old dust covered relic in the Air and Space Museum from 50 years ago. It's the real deal.

So I had to sneak in and take a couple pictures with my cell phone. As far as I could tell, there was only one member of the press there in the cold tent, and the Tesla workers were looking at me funny, so I didn't stick around long.

Oh, and here are some cool electric cars. I'd love to have one for fun.
