It also served for many other rites for our group and also visiting groups at times .
The black plastic walls were a great 'unconscious innovation ' ( meaning that effects were realized later ) in that , if no specific background is there in dim lighting , it either 'fades off into the distance ' as well as allowing a 'blank imaginative screen' all around .
One classic remembrance was Fr . 'J's initiation ... just as he emerged from darkness into light , a huge near directly overhead lightening strike went off . Huge blinding white flash ...Man his face !

but then for about a minute all I could see was a reverse negative image on the black walls wherever I looked .... (Its still with me that image ) .
Another time, there was a flood and a few people stuck here for a few days , camped out in there . Sand floor and a central fire ( as the roof was vented for that purpose ), kept things warm and dry , we even dried out two tents and sleeping bags in one end .
As I said elsewhere , you could trace sigils in the sand , fill the little 'troughs' your finger made with spirit and set them alight - flaming sigils at night .
many a rite from Rites of Eleusis was performed in there as well . Initially the temple cost $200 to make ! - all black plastic, but later I replaced the roof with clear plastic and shadecloth , much lighter in there at daytime .
We had a massive party here ( my whole site ) once ' The Gods of Olympus' , fancy dress , come as a God/dess . Friend and I put a LOT of prep into that ; installations etc . Various areas and buildings were 'temples' for various Gods . He wanted to be Hades and made the temple into a 'journey through hell ' with various weird sculptures, installations , weird art ( like Goya's Saturn ) , hanging chains , etc . and when you got through that maze to the center , he had set his throne up there .
I also adapted the roof to be able to open with a system of pull ropes and weighted cantilevered bamboo roof joists - great at night time .
