@Max: drinking classes?

Didn't think you'd need classes to teach you how to drink. :-)

@Neill: ...why not go the whole hog, and move the LEDs also...

I bet you could get some awesome effects

@David: Brilliant!!  With a design team like us Max should have his super-wormhole going in no time!

A loyal design team would build me one for Christmas LOL

@David: Max has got plenty of ideas to play with :-)   Just not the time :-(

Oh so true -- "work, the curse of the drinking classes," as they say

@salbayeng: ...if the back mirror was on a flexible substrate, then you could contrive to change its curvature...

Oooh, tasty!

One thing I REALLY like is that Missile-launching type power switch at the beginning of the video.....

If you're moving the mirrors, why not go the whole hog, and move the LEDs also.  You wouldn't need to spin them through the full 360°, just enough to move them from one position to the next.

@Salbayeng...

> "Hmm , but the viewing angle of each LED changes as you move into the spiral ? maybe?"

This still implies a line of leds going down to the bottom or the mirror.  You could use a spiral of the Adafruit Pixels, you would probably not notice that they were spirals not multiple circles, and you would effectivly then have individual LED control over a simple interface.

All these are really more complex variants of a kid's kaleidoscope and you coupld probably do the same just with mirrors?  A lady I know did some photos of flowers and such like through a home made kaleidoscope type thing she made and they are great

It's also used in car headlights for adjusting and aiming them, that's where I got the idea....

> Max could re-purpose some of the little electric car-mirror actuators?

@David  re "you could have a fixed (but slightly moveable) mount on the back mirror at 9 o'clock.   ...."  

You've pretty much described a "kinematic mount" , laser physicists use them all over their optical benches. They have a ball bearing in the SW corner, a 1/4-40 leadscrew with a rounded end in the SE corner , and another in the NE corner. (The back of the mount has two slots and a flat face in the approriate corners) there is a spring in the middle of the three contact points to keep the mount loaded up against the three spherical points.

Max could re-purpose some of the little electric car-mirror actuators? Maybe some muscle wire? Piezo stack?
