New: a Music tab, and DJ Beat Maker in it. A cat in headphones builds a track one cell at a time, across eight genres and forty eight tracks. Watch it build, or switch to Build and tap in your own. House and lofi are free. Every sound in it is generated in code, the same as everything else here. Nine more simulations: Chaos Fan, Trim Tower, Drop Shaft, Colour Peel, Sort Line, Split Bar, Chord Web, Ring Shed and Ink Reader.

Nine new machines, bringing it to fourteen. Escape Ring. One slips out of the gap and two more take its place. Double Drop. Every dive it takes twice as much. Flood Race. Boxes race a rising flood through a maze, with weapons on the floor. Square Wave. A sheet of cubes standing a wave on its corners. Number Mill. Two rooms grinding the same numbers down. Growth Chamber. It gets bigger every time it touches the wall. Duel Dish. Two of them, one dish, and whatever they pick up. You can put your own photos on the fighters. Big Bite. It eats everything it can reach and comes back bigger. The camera pulls away as it grows. Thread Loom. Balls tied to a ring, cutting each other loose until one is left holding. Every machine can now export a clip of a whole run with its sound, watch it back, and save or share it. Three new voices that are generated rather than recorded, so they stay in tune at any speed: Music Box, Kalimba and Harp. Picking a sound in Settings now plays it. Louder colour palettes on the field machines, and the sliders now show what they are doing while you drag them.
