This needs to be an augmented reality mobile app. The problem on the AI side of things is that a good algorithm that reliably "learns" what Waldo looks like would need a substantial number of examples.

A good solution to this would get close, then calculate the probabilities of every "maybe-waldo" and then display the one with the highest probability of being Waldo. An augmented reality app that highlighted Waldo on every page would be awesome.

If you've got net access (or even if you don't), it seems almost plausible that you could just identify the book/page in question and use a lookup table of coordinates.

I don't know how many variations on the /Where's Wa[a-z]+\?/ theme have actually been produced, though, so maybe it wouldn't be easier.

Then again, if you can upload unknowns, wait until you've got enough samples to generate confidence, and then store the result, it'd scale/perform much better :)
