There’s a great free online tool called the Rasterbator, what does it do? “The Rasterbator creates huge, rasterized images from any picture. Upload an image, print the resulting multi-page pdf file and assemble the pages into extremely cool looking poster up to 20 meters in size.”

It’s simple: Upload your JPG file to the Rasterbator and it spits back a printer-friendly PDF. Use your trusty, or crummy, inkjet (or better yet, your work laser printer) and a few minutes later you’re holding a Rasterbated bundle of sheets ready for assembly into one chic wall mural.

You can also get Rasterbator as a free desktop application for Windows
