I'll definitely have to check it out.
Decades ago, I knew a guy who worked as clerk in a porn store, just as video was taking over the medium. In those days they had film loops in the viewing booths for the pervs to watch. My buddy was a film student, in his spare time at work he would splice art scenes and religious bits into the loops, just barely long enough to be seen for about a half second, but not long enough to be comprehended. He found that this was best for putting a "WTF?" look on the pervs faces, but not ask questions when they came out of the booths.
When his boss finally caught him doing it, he canned him. However, the local papers picked it up, making him a local celeb, and getting him a few offers in the film industry, one of which he took. As a far as I know he's still on the West Coast working in the industry.
