Here is such a stunning effect our installation will do. The effect is clearly observed in a dark smoky space.
I pasted the mirrors onto the CD. You can make these mirrors from another disk, but it's better to take real ones. Gluing is also necessary well, so as not to fall off. Then I put all this stuff on the old player so that it would spin. I just did not want to bother and attach the motor. So I made a quick hand. See photo:
Then I aimed a laser pointer at these mirrors, at the corners as in the picture below:
And voila! It turned out a little magic!
Well, how do you arrange your installation - you decide!
