Stained glass is something Jewish kids can enjoy while guesting in their Catholic friends' cathedrals (like what happened to me on Sundays after sleepovers). If only all stained glass windows were this geeky.
This Mario Bros. mushroom was created by artist Radiance Art with over 80 individual pieces of glass. It's mounted in a 15-inch square zinc frame and you can pick it up on Radiance Art's Etsy page for $US175 (USD).
Building a Church of Mario to put it in, however, will be the real drain on your wallet. Especially if you expand the concept to a Church of Nintendo and commission Radiance Art for Pac-Man and Zelda stained glass windows.
