Math whizzes finally have a lamp they can sink their number-crunching teeth into. The Calculating Chalkboard Lamp by Mingyu Jeung randomly generates a math problem that must be solved in order for the lamp to turn on. The whole light is set in chalkboard so you don't need to use your brain.
I'm all for stimulating my brain, but I'm terrible at math, and I can't help but wonder how I'll see the chalkboard to figure out the math problem without a light.
