It's already considered a grind to produce stop-motion video -- imagine creating a clip using the spreadsheet app that many dread seeing at work every morning. Joe Penna, better known to the internet as Mystery Guitar Man, isn't afraid. He and his team recorded a performance against a greenscreen, gave the video a mosaic look in After Effects and proceeded to recreate 730 of the frames in OpenOffice (and occasionally Excel)... by hand. We don't want to know how long it took Penna and crew to wrap up their work, but the result is probably the liveliest you'll ever get out of an app meant for invoices and corporate expenses. The fully produced video is above; click past the story break if you want to smash illusions and see how the pixelated rumba came to be.
