What is this moving mirror?

[dbuckley]

Got to see The Pink Floyd Experience^* last week, and they had a moving mirror thing I haven't seen before. Some person has helpfully posted a cellphone vid of part of the concert, which I've put below. And I do mean moving mirror, not a euphamism for a fixture with a lamp and a mirror, just a mirror. And I'm pretty certain this is a first surface mirror, as they bounced frikken' lasers off them. The moving mirror is mounted atop a stand, and below that can be seen the laser (the black box thing), and lower still what looked like a discharge fixture of some sort that didn't move at all.

 

This is the best pic I can find of them:

At 5:02 they get illuminated, can be seen fairly clearly at 5:54, and at 6:04 they start to revolve in one axis. They are positionable and steerable in both axis, as can be seen at around 8:43.

 

I've googled and have a long list of things they are not, the nearest being a Studio Due light deflector or DMX360, but although these things appear functionally equivalent, they look very different to this mirror thing.

 

Anyone know what the mystery object is?

*) There appears to be at least three bands with the moniker Pink Floyd Experience, this is the Kiwi version, there is also a UK version and an American version. Based on nothing more than YouTube, if you want to listen to the music of Floyd then the Kiwi one is definitely the one to go to listen too, though the American version has a very big moving light rig and does some very impressive things with it.

Hard to tell from your image, and to be honest, I haven't had a chance to look at the video but it could well be the VLM from Vari-Lite. I think it was a series 300 yoke with a double sided mirror from memory, it's been along time since I've seen one and they weren't that common anyway.

 

There is a spec sheet on the Vari-Lite website with a picture. Looks reasonably similar to your image.

They are indeed VLM's

 

Very handy, more often than you'd think...

That appears to be the bunny! It did look like a mover that someone had swapped the gubbins for a mirror.

 

Looks like someone has scoured the world for discontinued product, and they are now corralled in little old NZ.

 

Thanks all.

 

E2A: Now I know what they're called, the third hit on google is this video of the exact assembly as a prototype. And what I described as "looked like a discharge fixture of some sort that didn't move at all" appears to be a cyberlight minus its mirror. This is Kiwi number 8 at its finest :)

The Australian Pink Floyd Show were using something very similar when I saw them at the NIA. Fantastically well designed lighting.

An arms race betwixt the Floyd clones.....
