If you're going to have a geek inspired jack-o-lantern then why stick to those pesky candles? Not only does it light up with LED lights it lights up in three separate colors.
The video tutorial shows you step by step how to cut out the Mario mushroom and then how to hook up the shiny lights. A small suggestion, don't put it outside till it's completely dark because this is one design that looks really ugly with the lights on. You can't even tell the thing is a mushroom.
However, to make up for it once night falls it looks extremely cool. The lights shine in green, red and blue. To see the video check out the link.
