There's no real market for applications written for Google's Android cell-phone operating system — the sad, software-only remnant of the abortive quest for a Googlephone — but Google's trying hard to create an artificial one. Participants in Google's Android Developer Challenge submitted 1,788 Android programs. In May, Google will award 50 semifinalists $25,000 apiece. Eventually Google will pay out $5 million in prizes, or about $2,800 per entry, according to quick bit of math. Why not actually make a Googlephone? That seems easier. (Photo by Kai Hendry)
