Rasterbator Edit
Print your own posters.

I rasterbate a lot. And you should, too! It’s good for you and it won’t make you blind, either…

Here’s what it says on the website: “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.”

Try it. But just watch out - before you print a hundred pages…
