Quite possibly the coolest thing ever (at least until the next cool thing that catches my attention...) - Rasterburation. A simple idea (always the way), but with many possibilities. The Rasterbator rasterizes any image you upload, so that you can enlarge it. And that's where the fun begins - you enlarge your image and then print out your image on multiple sheets of paper. Each sheet looks like nothing much, just a bunch of dots, but put together and viewed from a distance and you've got yourself a masterpiece!
Here's a cool example from the Rasterburation gallery:
I've got the inklings of a crafty idea brewing in my brain - surely there's a way to make dots out of something 3D or doing something stitchy. Ponder, ponder...
