Last year, GeekDad's Dave Ebanks went to a local printer to similarly blow up an image of his son's favorite race car but it cost him a bit of a bundle. I recommend that you either purchase extra-thick paper or use photo prints. It results in a cool optical illusion when it is placed on the side of a building - up close, the images are weirdly indistinguishable, but from afar, they look just right.Īlso, the sheets of paper I used (regular Staples inkjet white paper) proved to be far too thin and flimsy, even as the picture came out clear and colorful.

This points to a couple of the app caveats: The smaller the original image file is, the more likely it’ll be pixilated when it’s blown up. It took ages! I then printed each file as 'fit to page.' The resulting poster looked really cool - we really liked the pixelly/blocky look - each pixel printed out around 1cm squared.' I manually spliced it up in MS Paint(!), counting pixels and saving each segment to a separate file. Blockposter creator Steffan Luczyn told us the laborious process of cutting up images to crate a poster is what made him come up with the idea to automate it: 'I decided to make a poster for my girlfriend from a (really) small picture she had of Dave Grohl (Foo Fighters).
