Jerry Jalava has built a special prosthetic finger which contains computer storage for photos, movies and other useful files.
While the prosthetic looks like a normal finger Jerry can peel it back from the 'nail' and plug it into the USB slot on his computer using it as an additional hard drive.
The finger is not permanently attached to his hand meaning it can be removed when plugged into a computer.
The ingenuity of Christmas gifts has inspired Dr Strabismus (Whom God Preserve) of Utrecht. He has invented the perfect gift for anyone who knows what he doesn't want. It is described in an advertisement as an oblong wooden peg which props up a built-in sieve. The angle of the sieve makes it possible to sift things sideways, so that what falls through goes into a bucket clamped vertically to the wall.
