SpatialNote is a 3D note-taking software. The workspace consists of cubes. SpatialNote allows for working with details from the inside the cube view, and with the big picture from the outside structure view. The idea behind making a 3D note-taking solution is to include spatial memory into the process, and boost memorization by implicit spatial metaphors.The application doesn't require any special skills in 3D.
