I am quite lost for words. I would put it in the "fund it!" pool, if it wasn't for the fact that it apparently already exist!

I love how they show example on how one could use this pillow haha

Geometry quiz time, assuming all the edges are perfect straight lines that intersect with other lines in 90 degree angles, how long (in centimeters) are the 2 unlabeled edges?

That's not even geometry, but simple subtraction, since all angles are 90°.

That last example....pretty fuckin classy.

I wondered who would buy...
