The spinning cage thing immediately reminded me of the Dreamachine of William S. Burroughs, Brion Gysin, and Ian Sommerville.
The device uses the flicker effect to create brainwave changes in the viewer. I met a guy once who had a helmet which produced similar effects couple with sound frequencies. Never got to see the thing in action, which is probably for the best. He *cough* may also have been a member of the OTO, Temple of Set, and military intelligence.
I built a dreamachine once from heavy paper. Fairly easy, there are patterns all over the internet, except obtaining a 75 RPM turntable can be tough these days. It actually makes a stunning art piece, I made another for ornamentation with colored tissue paper in the slits.
When I tried meditating with it I got some interesting color and pattern effects, but no deep trance. But then again I don't go into trance easily.
