swami_worldtraveler has created some interesting Photosynth’s. The screenshots were chosen to be visual compelling, and to cover a broad range of features, user controls, and user interface particulars. Highlighted ruins include the Temple of the Inscriptions, a grand view of the site, and the skull from the Temple of the Skull. Totally new to most, and hopefully exciting, is the 3D "point cloud" model resulting from the synth. Exactly what this is will be come clear below. 

Go here Mayan Ruins of Palenque and take a 3's the charm! or reffer this quick quide.
