To be honest, I had a hard time finding anything I thought was compelling at all.  Most of the experiences I found were either game or advertising-related, none of which I found interesting in the least.  The best example I found was still game- and ad-related (could be construed as a promo for the magazine), but I guess I thought it was silly for silly’s sake, and that made it less annoying.  My impression from what I found is that there were lots of monetization attempts, and little creative or innovative thinking going into AR experiences, at least the ones that get high-ranking google searches or made it onto youtube.  I really thought I’d find more cool stuff…  I wouldn’t use any of the experiences I found in an AR project.  I’d try to find something that was actually useful and not just a re-hash of what’s already been done.  But I guess that’s hard.
