There really is no end to the USB gadget universe. Case in point: "Jones's Mr. Tengu," a USB character that Solid Alliance devised with London designer Crispin Jones. When you connect Mr. Tengu to the USB port of a computer a red LED "face" appears and reacts to the sound around the room. As sounds change, so do Mr. Tengu's faces. Make him mad and you've got a grumpy, robotic USB on your hands. I wonder what happens when you play Rihanna?
