Looking for the perfect gift for the math geek who has everything?… or the math geek who has nothing? How about a brightly-glowing Pi symbol? Contrary to the mathematical constant, there’s nothing irrational about this thing, but it will constantly glow when you hang it on your wall.
I spotted this geeky Pi art over at LuxChroma’s Etsy shop, and it’s quite the thing for the math-obsessed out there. While you probably can’t use Pi in an equation to determine the size of this thing, I’ll tell you that it measures 15.5″ (w) x 15.25″ (h), and is constructed from durable PVC, with bright LED backlighting. The default version comes with green illumination, but can be requested with white, blue, red or amber LEDs too.
Mathematicians, you can grab your glowing Pi wall art over on Etsy for $65 (USD). If you’re more into computers than math, be sure to check out the glowing 5-1/4″ floppy disk or USB symbol, and Mac users will enjoy this glowing command-key symbol.
