A browser extension that removed baby pictures from your Facebook newsfeed by replacing them with something better, like cats.
Developed as a response to the onslaught of babies cropping up on Facebook, Unbaby.me quickly became a news sensation around the world, generating everything from segments on Ricki Lake to half-page spreads in The New York Times, making it one of the most talked about interactive projects of 2013.
Unbaby.me worked by scanning your Newsfeed for keywords and phrases (too precious, looks just like mom, adorbs, solid foods), and simply replaced the associated content with images from another source. Made in under two weeks for less than $500 dollars, Unbaby.me literally gave birth to the trend of extensions replacing things with other things.
Note: the extension is no longer available, but there may be suitable alternatives out there.
