It's an interesting article. But I hate the header image. It's cool and all, but has nothing to do with psychedelic hallucinations. And while Klüver's "form constants" are OK, what's interesting about hallucinations isn't just the basic geometry.

Consider LSD hallucinations, for example. I recall especially complex entangled "ropes". Brightly colored, and in constant motion. Both spinning on axis, and writhing. But the motions weren't just three dimensional. There was a sense of stuff rotating and moving through other dimensions.

Also, the "ropes" had lots of detail. Almost like strings of characters. A little like that G/E/B block on the cover of Hofstadter's GEB. I also recall this guy who argued that all Hebrew letters were two dimensional projections of some multidimensional object. He released a video, which reminded me of LSD hallucinations. Very Kabalistic. And perhaps one inspiration for Aronofsky's "Pi".
