First… get your mind out of the gutter… this has nothing to do with what you think it does. Â The Rasterbator actually is a pretty cool site/tool that I forgot about until it recently came up in conversation. Â Anyways, what it does is it allows you to take any image and turn it into a dot matrix so that you can blow it up across multiple sheets of paper to wall size if you wanted to. Â You have two options to use: their online version or download it. Â The self-install is better if you have a larger image as it doesn’t have any size restrictions. Â I believe you can customize the number of sheets of paper and also if you want it in color or grayscale. Â Mostly, we’ve used it for office pranks such as when my former boss’ wife had a baby, we photoshoped one of our co-worker’s heads on a baby body for a congratulations sign. Â Or when we photoshoped another co-worker’s head on an image of a person wearing a unitard and the boys put in in the bathroom stalls.
