Below and on the following pages are many photos from Burning Man 2002 with descriptions of the Conic Shelter art project that was featured as part of the Point Arena camp. This conic (called the Arena conic) displayed a number of firsts including the first full field tested "horn," or unsuported intersection of three inverted cones (see below). Also this was the first cone to be constructed in position rather than assembled flat on the ground and then winched up into the conic shape. The performance of the conic went beyond my expectations. Many thanks to Dan Doyle, Richie, Andreas, Michael Jeremiah, Ian, Mandy and the dozens of others who helped make this Conic happen.
To the left is an early computer model of the Arena Conic. In the foreground a 6' female model is standing next to the generator pole so as to show the relative height of the plywood and give a sense of the headroom that would be available near the corners.
Bear in mind that the corners come together at an angle slightly larger than 90 degrees. This facilitates furniture, desks, bookcases, and other objects in a completed Conic Shelter.
Here's an oblique aerial rendering. You can see the four "peaks" or apexes from this angle clearly.
The peak in the middle I've come to call a "horn" because it resembles mountain formations like the Matterhorn in Switzerland in that three inverted cones come together to form the peak.
I was pretty confidant that the horn could hold itself up without a tripod support (as in the other 3 peaks). But this was unproven in the field. As you will see in the photos below, the unsuported horn showed no signes of deformation and remained completely stable even with several people standing on it during 40+ mph winds.
From this perspective the horn (middle apex) is visible from a different perspective.
Here's the as-built photo of the conic. The Point Arena Theme Camp (Arena Aquarium) used the Conic as their stage complete with lights, music, dancing, etc. They did some delightful creative things with those lights and canvas walls (see below) including a full-blown go-go cage surrounded with L-wire lights.
OK... let's start from the beginning and go through the conic building process in some detail.
