Toasty! v2.0 USB Heating Slippers
First we had USB heating gloves, which were a decent idea, although it's probably difficult to type with gloves on. Now from the same company there are USB heating slippers, which are a novel idea. Get up from the computer, put them on and simply plug them back in when you return. Oh, Universal Serial Bus, how I love you so.
