I was just looking at the i-nigma reader (via Internet Archive) for Windows Mobile.
If you have it installed, you can point your phone’s camera at this image and then call me… crazy!
Update: Looks like Microsoft is working on something similar (via Internet Archive), but broader in scope and uses. Sweet!
Update (2024): “this image” has now been lost to the sands of time (internet)…the original image was a QRCode with my contact info. ¯\_(ツ)_/¯
