Photoshop: after 20 years of making celebs look thin, a big cake

Happy birthday to you, happy birthday to you, happy birthday dear, er... Photoshop , happy birthday to you. It might have passed you by, but it's Photoshop's 20th birthday! Here's a cake to prove it, although frankly it's a lot more wrinkly and tired-looking in real life. Unfortunately the four founders of Photoshop were unable to share the cake with us, but you can catch up with them and enjoy a little nostalgia – ooh, look at the funny Mac! – here. The reunion meal, from about two minutes in , appears to have been inspired by the old comics sitting round a table at New York's Carnegie Deli in Woody Allen's Broadway Danny Rose . It's even got a comedy jazz score in the background. "Twenty years since we've been in the same place at the same time in the same galaxy..." Memories, eh?
