Just in case it's not completely obvious you're a geek...
This USB-powered replica of the TARDIS from (do I need to tell you?) Doctor Who is a delightful 4-port hub. When plugged in, the blue light on top activates. As you plug in other USB devices, the TARDIS' "engine" plays that unmistakable sound of the TARDIS materializing. Plug in your USB mouse and watch for Rose to come a-runnin'.
