Indoor in a museum or public space 25 x 25 feet / 8 x 8 meter, ceiling height 20 feet / 6 meter, round or square shape, can accommodate and mount technologies such as projectors and speakers. Hollow sprung floor, no window/natural light source.   

The 2 hour visual of Buddhaverse, HEART Mandala, is complete, and I have a 24 feet diameter parachute. I've been partially mocking up the installation, and need a bigger space for full production. I'd hire a technologist for the interactive software.
