Papervision Augmented Reality (via OUseful)
By printing a little square pattern, using my webcam, I got this little creature to appear on my desk:
It was a little fragile — I couldn’t get it to appear reliably and it disappeared when I moved it.
I can’t wait to try out the native code apps for the iPhone (lots of cool links at OUseful)… reminds me of the VR-GPS art installations in Spook Country by William Gibson which I just started reading.
