from time to time i have ideas for things. i got this idea from a police facial recognition device...it would take a picture of the person's face, then go through a registry of convicts to see if that person was on file and if he/she has a warrant for their arrest. i like the idea of that, but used in a different way. what if i had just an internal memory that had a picture of every type of shoe...and when you take a picture of shoe X...it would look for shoe X in the internal memory of the device. wouldn't that work?
