Insulation (Where shall I stage my MashUp?)

I've looked around the Oscroft area to try and locate where I can show my video on and where it shall be staged at.
At the moment, I've found some windows halfway through the hallway that's connected from the entrance of the Oscroft centre, to the 3D room and the Textiles room, and then to the 2D room, which both walls have windows which belong to the 3D and Textiles are facing each other. My idea with them is that I can put the projector on one side of the window and block the other window from the other side of the window, to make sure the video does not go through the window, and maybe block the other window, but cut a rectangular opening for the video to project on the other window for two reasons, to block the sight of the projector's location and try to block out any unwanted light from behind and around the projector, that way, the video is more clear for the viewers to see the video clearly without any light by in the way of the projection, however there could be a problem, passer-by's will walk pass the video, this will block the projection or cast shadows on the screen.

In the Textiles room, there are some cupboards inside the room, beside the outside windows, I had two ideas with cupboards, one was to let the cupboard doors closed and projected the video on the cupboard doors, but the problem is that, the colour of the cupboards are striped in black and white, and my video is in colour, this will mess up the colour of the video and the image, plus it'll be irritating to see the video on. Or, I can ask if I can move all the equipment from the inside of the cupboard and place a screen in the middle of the cupboard and maybe place some extra stuff around the video, and maybe I could let the viewers to open the cupboard to see the video on the inside, However, the video will also share the same problem, since the video is being projected around the room, passer-by's will walk pass the projection, blocking the video and casts shadows on the projection.
