Trav and Kelly, of course there is a trick. This is basically a 360 degree panorama, stitched from several single shots with PTGui. The perspective was achieved by playing with various projection settings; I am not quite sure but I think it was "stereographic down". The photos are the same that I used for the entry "My Own Little Planet"in Jano's "Private Worlds" challenge (CIC 8) but due to the different projection the result is turned inside out. -Gerald
