The three sources I would recommend to find features are searching this forum, watching videos of people using sandboxes, and reading the source code. I do not know a sales pamphlet type of listing of things one can do with an AR Sandbox.
Thanks Sean, I’m particularly interested in display a satellite image on the sand after building the topological shape from a DEM (From version SARndbox-2.2 and on is possible to load and save DEM). Do you know if is already available?
According to this post by Oliver, no, the sandbox software cannot display an image file.
However, this video shows someone projecting an image using other software on the desktop (it looks like Eye of Gnome aka Image Viewer, to me). Remember that the projector is just another monitor to the computer and you can drag application windows onto the sand surface.
