The best thing about a great Lego creation is that you when you get board of it you can modify it into whatever you want. Check out this pair of heads created by Julius von Brunk. The Lego head features movable eyebrows, a compartment inside the head, and the option to wear glasses. One such version called Shock Treatment (above) features built in lighting that is stored inside. It would make a great and creepy nightlight. There is also Game Over (below) which incorporates a whole lot of transparent red pieces. Originally the effect was done with a solid red, but ended up looking too cartoony.
If you want to see more of the Lego head project check out the album over here, there are over 10 different versions: https://www.flickr.com/photos/baronvonbrunk/albums/72157668738617282
