Getting a good projector in Nairobi was challenging. After we came across with a couple of projectors really old and unacceptable shape, we finally found one. This guy was 15000 lumens, fair enough to light up a building given that there is no much public illumination on the street we were working on. Unfortunately
Some of the demos we were able to run was a PACMAN controlled by custom controllers and particles system following your movements.
