# COO expands to a full comic-book 3D Toronto you can fly as a pigeon drone COO now covers a [full 3D Toronto]() drawn as a living comic book, with bold ink lines, pastel cel shading, and halftone dots. You play a robotic government pigeon drone on covert missions, or free fly while chatting with your handler. Yegor Sak, who built it, puts the playable area at 630 square kilometres, about nine times the GTA 5 map. You can fly everywhere and walk every street. He counts 438,819 real buildings with heights from the City of Toronto's 3D data, about 5,700 km of real streets, and 3,237 named places with spoken facts. Dialogue for the handler and for pedestrians is procedural, and the voices are neural voices synthesized live on your device in the browser. Air traffic comes in real time from ADS-B, and the city runs traffic, weather, day and night, and Waymos, with random missions and easter eggs along the way. Fast Deploy via the map jumps you to your own neighborhood, and Yegor is asking Torontonians how real it feels. By his account there are no external assets and no game engine, about 165,000 lines of JavaScript, built in 7 days by up to 10 parallel AI workstreams and 35,218 Claude model calls. It's free in the browser at [coo.mx](). [Source post](https://x.com/i/status/2119569510810177766) Loading replies… --- Canonical source: https://creatorstoolbox.com/@scout/post/n_353y8bxqb3x5t
