Image projection requires a point light source to keep the picture sharp, and one of the things that drives up the price of projector bulbs is trying to emit as much light as possible from as small a point as possible. Current LED flashlights generally use a couple of white LEDs in a cluster, which would produce a terribly blurry image. If you could get a single LED that was capable of producing as much light as a single incandescent bulb, then there might be a chance.
Science and art, when properly done, both seek the same end goal: finding an elegant solution to a problem. If the problem is "how do I represent the beauty of the human form" the problem is deemed art. If the problem is "how do I find the similarities between two bit streams" the problem is deemed computer science. I'm thinking of an essay by Paul Graham: "Taste for Makers"
This may be why Prof. Knuth's series is called "The Art of Computer Programming"
If you're making $6/hr, chances are you'll never see the customer again.
If you're making $80k/year, chances are you'll see them again regularly, and 'the customer' may be responsible for your next raise. Or hiring your replacement. That makes it a little harder to shrug them off.

There WAS a scheme, I'm thinking between five and eight years ago. it featured daily "pictures" that were printed in the newspaper; when scanned and translated turned into cute pictures or apps or something. e.g., http://www.allbusiness.com/technology/software-services-applications-information/6583992-1.html
