It'll take you a very, very short time to make a mosaic tile for the latest challenge from Inventables. I did mine in 10 minutes...and you can do it with a file you already have laying around. In exchange for helping them get into the Guinness Book of World Records they're going to send a $5 off coupon. Inventables will allow schools to combine gift cards so by combining our powers we'll get something really cool for our kids! Put your spam email account to good use
No CNC? No problem. You can still contribute by making a file and uploading it. I'd be more than happy to reserve the lecture hall and walk anyone through the process who wants to help but isn't familiar.
@uglyknees if we can really rally the masses I bet we can get two! Maybe the crack you need?
