What is PlaySpace's virtual sand tray?

It is a browser-based 3D sand tray where clients drag and drop miniatures to build scenes, with no mess and nothing to download. It has more than 500 stylized 3D figures, backgrounds such as jungle, beach, winter, space and volcano, and tools to zoom, rotate, duplicate, dig, fill, bury and paint. The sand tray is multiplayer, so you can choose to join and play alongside your client, and you can save a scene to revisit later.
