There are no shortage of strange USB peripherals that you can pick up, many in odd sizes and shapes. There are even USB drives shaped like sushi, not that I’d use one. One USB device that some might actually find useful is the Mini USB Piezo-Ionizer whose producer claims will purify the air in your workspace by producing a flow of high density negative ion output. You haven’t showered in days so you’d better pick one of these up quickly and get that air clean. $16.
