Move your pointer or drag a finger across the brain to reveal the magnifying glass. The glass disappears when the pointer leaves the brain or you lift your finger. It reveals a repeating pattern of the uppercase word BRAIN encoded as eight-bit ASCII: 01000010 01010010 01000001 01001001 01001110. With the illustration focused, use the arrow keys to reveal and move the glass, Home to recenter, and Escape to hide it.
