    "description": "Gravity Grid is heavily inspired by Go, a 2,500 year old board game. The game of Go is played on a 19x19 grid, which is how every Gravity Grid invocation begins. A psychedelic \"gameboard\" is drawn and pulled apart by gravity, as if slowly orbiting a black hole in space. Each Gravity Grid starts at a different stage of this process. Don't forget to click and hold - you *might* find an additional effect.",
