"Mind-Bending Monday Challenge: Unraveling Illusions with Gizmodo"

Gizmodo presents a collection of optical illusions and puzzles, including the Neural Correlate Society's Best Illusion of the Year contest winner and a mirror demonstration. The article also features two mental illusions puzzles, one involving ants walking on a meter stick and the other involving a rectangle inscribed inside a quarter of a circle. The solution to last week's puzzle is also provided, explaining the concept of divisors and how perfect squares are the only doors that will be open at the end.
