Check out this Doctor Who Tardis USB Hub With Sound - reduced to just £14.99 delivered from Play.com. This is quite a quirky little item and would make a lovely prezzie!
Description: 4 Port Powered USB hub - allows you to connect multiple USB devices to your computer. You can use the TARDIS as a non-powered hub as well by just plugging it into your USB port and not using the power supply it comes with. When you plug it into the USB port on your computer, the blue light on the top lights up and when you plug anything into the TARDIS itself, it makes the 'dematerialisation' noise and the light slowly flashes on and off. There is a button on the back to switch the sound off if required.
