A Dreamachine consists of an upright cylinder with patterns cut into it and a lightbulb suspended at its centre. When spun on a turntable at 78rpm, the flickering patterns (viewed through closed eyelids) can cause trance-like hallucinations.

Interestingly enough now that you point it out, said instance of craziest visuals I've ever had was against the backdrop of a ceiling fan...
I had not even considered the potential relevance of that before

TBH one of my favorite "trip toys" is basically just a white ceiling fan, with a TV turned on (and muted) in a dark room...

You just lie underneath the fan (listening to music, obviously lol) looking straight up at it --ideally the TV itself shouldn't be within view-- and as the fan spins, the blades will pick up the colored light from the TV.


Of course, the light patterns will change (more often with some programming than others, but music videos seem to work well). And as you begin to trip harder, the spinning / colors/ light reflections can get pretty funky, make some interesting patterns / shapes, often seem to synch when the music in fun ways, and sometimes has an almost hypnotic effect.

(Oh, and bonus points if your white fan blades are held in place with polished metal, as that will really pick up the light, and makes the inside of your fan-dala™ really pop.)


Simple, but way too fun when you're tripping.


Obviously I discovered that one accidentally, quite naturally in the course of events one night... but after that I always wanted access to a ceiling fan for psychedelic reasons.




Kinda bummed my current bedroom doesn't have one. (And I rent, so fuck me.)


Anyway, that being said, I have always wanted to experiment more with light induced effects on consciousness...

Spikes are metabolically expensive to produce," says lead author Kristin Koch, a PhD student in the lab of senior author Peter Sterling, PhD, Professor of Neuroscience. "Our findings hint that sluggish cells might be 'cheaper,' metabolically speaking, because they send more information per spike. If a message must be sent at a high rate, the brain uses the brisk channels. But if a message can afford to be sent more slowly, the brain uses the sluggish channels and pays a lower metabolic cost."

"In terms of sending visual information to the brain, these brisk cells are the Fedex of the optic system, versus the sluggish cells, which are the equivalent of the U.S. mail," notes Sterling. "Sluggish cells have not been studied that closely until now. The amazing thing is that when it's all said and done, the sluggish cells turned out to be the most important in terms of the amount of information sent."
