The Electric Kool-Aid Acid Test

p206:

For months Kesey has been trying to work out... the fantasy... of the Dome.
This was going to be a great geodesic dome on top of a cylindrical shaft. It
would look like a great mushroom. Many levels. People would climb a stairway
up the cylinder - buy a ticket? -- we-e-e-ellll --- and the dome would have a
great foam-rubber floor they cold lie down on. Sunk down in the foam rubber,
below floor level, would be movie projectors, video-tape projectors, light
projectors. All over the place, up in the dome, everywhere, would be
speakers, microphones, tape machines, live, replay, variable lag. People
could take LSD or speed or smoke grass and lie back and experience what they
would, enclosed and submerged in a planet of lights and sounds such as the
universe never knew. Lights, movies, video tapes, video tapes of themselves,
flashing and swirling over the dome from the beams of searchlights rising
from the floor from between their bodies. The sounds roiling around in the
globe like a typhoon. Movies and tapes of the past, tapes and video tapes,
broadcasts and pictures of the present, tapes and humanoid sounds of the
future - but all brought together *now* -- here and now - Kairos - into the
dilated cerebral cortex...

The geodesic dome, of course, was Buckminster Fuller's inspiration. The light
projections were chiefly Gerd Stern's, Gerd Stern of the USCO group, although
Roy Seburn had already done a lot with them and Page Browning showed a talent
that suprised everybody. But the magic dome, the new planet, was Kesey and
the Pranksters. The idea went beyond what would later be known as mixed-media
entertainment, now a standard practice in "psychedelic discotheques" and so
forth. The Pranksters had the supra-medium, a fourth dimension - acid - Cosmo
- All-one - Control - The Movie ---

But why a dome? The answer to all the Prankster fantasies, public and
private, the whole solution - they already found it; namely the Hell's Angels
party. That two-day rout hadn't been a party but a show. It had been more
than a show even. It had been an incredible concentration of energy.
