This is the Stepping Feet Optical Illusion. It demonstrates how high-contrast patterns interfere with human motion perception. Two colored blocks move at identical, constant speeds, yet appear to stagger and “step” like feet. A hover interaction removes the background grid to expose the mathematical reality of their parallel movement.

This is a DotLottie Interactive Sparkle Header. It blends high-performance character-level typography effects with the modern DotLottie animation format. Its function is to create a delightful, “juicy” hero interaction: when a user hovers over the title, the letters individually react with a staggered lift-and-tilt motion, while a complex Lottie sparkle animation plays in the background.
