I saw these cute little lamps done by Bena (bena_rt). My family has been playing a lot of MarioKart lately, so the Mario and Luigi figures jumped right out at me.
The blocky style of a simple LEGO mosaic works well in portraying video game characters. The way the figures turn the corner of the lamp is fun, and the fact that it all lights up is a brilliant idea (pun intended; sorry!).
