My desk is often covered with cables (especially when I am recharging my portable devices), so I thought it would be fun to help conceal the mess by using a USB Hub that looks like a toy firetruck. See, all the wires/cables would look like hoses when plugged into the side of the firetruck.
For increased functionality I would also include a headphone jack, card readers, and an LED lamp built into the extendable ladder. Lights and sounds would also be a fun touch.
