How we create it
A Window on the world can, be achieved through a selection of technologies. For concept mentioned above, we decided to go for rear projection as we had available space behind the "window". We calculated the mirror size and looked at the gain of the rear projection screen. We checked the amount of ambient light and calculated how bright the projector needed to be, to overcome the ambient light in the room, and found out that a Medea would do the job.
Medea is a 6500 lumens media room projector and for this size canvas it would be bright enough. We used our 90-degree 0.57:1 short throw lens.
