I Need Input

Input is a 3D synthesiser you control with your hands. Drag the corners to resize the cube. Drag the faces to rotate it. The shape you make is the sound you hear every movement changes the texture, pitch, and character of what you're listening to. Designed to be immediate. No menus to navigate, no presets to load, no wrong answers. Pick it up, touch it, and something interesting happens straight away. Five synthesis engines respond to the cube's geometry in different ways. A generative scene plays quietly in the background while you explore. There is no clock, no score, no finish line. Flick the switch in the top right and you're in holiday mode. Keep an eye out for the UFO, maybe if you tap hello, they'll show you something... Made for people who think in motion. Made by deciBelboy / Vest Sound Works.
