I do a lot of projection installations, in unique locations, usually with about zero setup time. When I looked into buying a professional 10’x7’ “fast-fold” screen, I was blown away by how much they cost. Instead, I decided to design my own, using easy to find materials.
The Challenge:
1. Fast to set-up
2. Fits in a cab
3. Front or rear projection
4. Affordable
Seej also has a page with advice for making your own projector mount to go with the screen.
