There may not be a better housewarming gift for a geek than the Super Mario spiral clock. This custom clock was created by Etsy merchant Backstreetcrafts and features some of the series' most iconic characters in all of their 8-bit glory. The Super Mario spiral clock is perhaps the only clock that will let you tell time using Yoshi and Mario.
Telling time is a little tricky at first on account of the clock's warped face. Upon closer inspection you'll see that all of the characters in the spiral are repeated in the same order, meaning that you can tell the time using any of the marked circles. Backstreetcrafts is selling the Super Mario spiral clock for 25 gold coins, or $25 in non-geek speak.
