This one definitely has to be my favorite Lego-themed gadget of the day! Measuring just 16x32x12mm, these tiny little Lego bricks are actually 1GB USB keys weighing a mere 6g. Available in five different colors, the USB Brick Key from SolidAlliance are also fully compatible with real Lego bricks so you can build a mice Lego sculpture to hide/store your key!
