Akai APC 40
Motu MK3 firewire
Sure SM 58
2 to 4 projectors
A space where to project on a 3 axis or even better on 4 sides of a cube, in our test we used the corner and ceiling of a room, but for the performance something large is needed.
Opaque plastic sheet / maybe scaffolding structures to make a semi transparent cube.
It can be on a building structure or in the inside of a large white room
