Google Arts & Culture app

Sure, we all know what famous person we vaguely look like (I always get Geena Davis, which ... I wish! She's still in a "League of Her Own.") But the blandly named Google Arts & Culture app will dig through thousands of museum artworks from days gone by to see if you have a truly old-school doppelganger.

It matched me up with numerous paintings, but the app's top choice was a Renoir. Although I doubt the woman depicted in his painting wore braces.

Twitter users are sharing their results online, whether or not they like the results. Even actor Kumail Nanjiani tried it out.

The app itself came out in 2016, but this feature is new. To try it out, download the app (link below), then scroll down to find the photo-matching game. Sadly, it's not available in all regions, so if you're not seeing it, that may be why.

When it works, it works. But you might not be very flattered by the results. Women are often matched up with old-style paintings featuring men with mustaches, and many of the portraits it searches are just not especially lovely. (Not everyone can be as lucky as CNET's Rebecca Fleenor, who just happened to be a twin of a famous painting.)

You can't simply upload your best-ever photo. You are supposed to take a selfie with the app and roll with however you look that particular moment.

But here's a cheat: if you have a photo you like better, the app will let you flip the camera around and photograph your photo, which can be fun. An 1980s photo of me worked, but when I tried to photograph a picture of my daughter and her cat, Google refused to play along.

The photo matching game isn't the only reason to download the app. You can also zoom into the details of famous masterpieces, take virtual tours of famous museums, browse artwork by time period and color, plus read various feature stories. A touching article on Anne Frank displayed a bunch of photos of her that I'd never seen before, including one of baby Anne in her mother Edith's arms at just 1 day old.

The app is available for iPhone or Android.
