There is one out there where you can take a picture of a barcode and it will look it up for you, tell you where to buy it and how much it costs. Very, very handy.

The picture in my avatar is of the Houston Ship Channel and was taken from my backyard. I like to sit outside and slap mosquitos while watching countless supertankers, barges and cargo ships of every shape and size carry all sorts of deadly toxins to and fro. It's really beautiful at times.....just don't eat the three eyed fish....
