Field notes
The editor treats each grid square as one metre: users paint surfaces and fixtures in 2D while a linked 3D view updates, then walk through the room. The homepage lists floors, walls, water, pillars, lights, doors, stairs and water slides, with fluorescent lighting, reflections and mood themes. Example rooms open in the editor, and a room can be shared as a link; the site says rooms are saved in the browser only.
