Infinipaint

InfiniPaint is a collaborative, infinite space, infinite zoom, canvas note-taking/drawing app. Unlike many other infinite canvas apps, there is no zoom in or zoom out limit. This means that this app is very good at things such as drawing sketches of the solar system to scale, or just drawing any massive objects with tiny details. Of course, this app is also perfectly well suited for use as a normal canvas.
