We’ve seen a real mouse who has passed on to the realm of heavenly cheeses, only for its body to be used to hold the innards of an actual mouse, but this time round his millionth generation offspring has the ‘good fortune’ to be turned into a USB flash drive in the name of science and hobby. Red LEDs have replaced its eyes, lighting up each time it is plugged into an available USB port. Definitely not for the faint hearted as steady hands and intestinal fortitude are a must if you wish to embark on this DIY project.
