This view of a Phota Tower Gallery is looking upward to where the spiral staircase veers off to the exit door, which leads to the Next Gallery.  Keyboard commands are available to move around Galleries, to rotate the viewer's perspective, and to look up or down.  Or just activate Explore to automatically stroll through Galleries, pausing to admire each photo.  In this case, the Gallery pictures were created by Kaleider and Liquib (this is the sample Album that is included with the Phota download).
