I should preface this "consumer tech" post by saying I generally do not give a shit about consumer tech. However, I love things that are A) dumb, and B) fun. If I can't explain why—even better.

That's why if you've downloaded the lastest version of Apple's iPhone operating system, iOS 11, there's really only one app that you need to enjoy its shiny new augmented reality features, and it is also the dumbest one. It's called Holo and it's a lot of fun if you don't care about using AR in an even remotely practical way. With Holo, you point your phone at whatever's in front of you and drop a little character in the frame. It might be a cop, or a soccer ref, or a guy who's fallen into a trash can, or Jon Hamm (yes there are a couple celebrity avatars, but they're the lamest part.)
