How Everything Is Made on Instagram: "This battery-free kinetic sculpture works on stored mechanical energy. With just a single twist, a hidden spring winds up — and as it slowly unwinds, it releases that energy into a series of precision-cut Eucalyptus and Ash plywood blades. Each blade is angled and spaced to create a continuous wave-like motion, so the energy transfers smoothly down the mechanism for up to 15 minutes of movement. There’s no motor, no battery — just clever engineering, frictio

Invention on Instagram: "Shredding an image into smaller pieces is a simple and effective way to understand the idea behind downsampling. When an image is physically cut apart and each small section is viewed on its own, the fine details disappear while the broader shapes and colors remain. This mirrors what happens digitally when an image is reduced in resolution. The computer keeps the essential structure but removes the smaller patterns that the human eye is less likely to notice at a smaller
