Do something useful with that camera phone

Cambridge University researchers have come up with something useful for the camera cell phone. Pictures like the one above called SpotCodes would be placed on things such as maps, packages and virtually anything. You point your camera phone at a SpotCode and click and it will connect you to online data associated with that SpotCode. NeoMedia Technologies has been developing stuff like this for some time. Applications for Symbian Series 60 OS phones are available at Bango
This reminds me of CueCats another early attempt at convergence between printed matter and the net. CueCats failed to really take off.

I need a freeware that generated SpotCodes. Sure beats marking my territory the old fashioned way. ;)
