No matter how small the act—whether it’s tying your shoe, or pressing a button, it’s all orchestrated by a complex system of nerves and what we call “gray matter”. While we think all our actions are random, these are actually a result of an intricate mental process. It is fun to discover how shapes, colour, and perspective can change a lot about the way we see things or fail to see things, for that matter. One thing’s for sure, we have one amazing brain!
