Interesting idea. I'm not sure how the color would be affected by projection on a yellow or green tent?
However say on a white tent it could be cool with low ambient light. It brings to mind having playboy foldouts pinned to the inside of our tents when I was a boyscout, and makes me think of sexting while camping as a new form of entertainment.
Did I actually say that? I wonder if I could get a good image projecting onto my white spectra pack?
