‘SmartLens’ app created by a high schooler is a step towards all-purpose visual search

A couple years ago I was eagerly expectant of an app that would identify anything you pointed it at. Turns out the problem was much harder than anyone expected — but that didn't stop high school senior Michael Royzen from trying. His app, SmartLens, attempts to solve the problem of seeing something and wanting to identify and learn more about it — with mixed success, to be sure, but it's something I don't mind having in my pocket.
