At ASIS&T two years ago, one of the folks from Microsoft Research was handing out little lenses to put over your cellphone camera to change the focal length so it'd work for scanning barcodes. (I'm only interested in this sort of thing as I deal with the Friends of the Library book sale, and I'd love to know if something actually has significant value and would be worth trying to sell through alternate means ... and I'm too cheap to shell out for one of the services where they modify your cell phone and you have to pay an ongoing service fee) -Joe
