3D printing service Shapeways are now offering QRCode stamps, so you can do cool stuff like this:
Here’s how they did it:
1. I went to a QR code generator, typed in the URL and got my QR code.
2. I opened the saved image in the Gimp and flipped it to horizontal(under image-transform).
3. Uploaded it to the Shapeways Stampmaker, ticked the for use with light box and ordered it for $25.
4. Shapeways 3D prints the stamp and ten days later I get it, and now I can stamp my QR code anywhere.
Which get’s me thinking, maybe we should try that first homework assignment again.
