Many people have made contributions to this project. First and foremost, Robert Cochran. He spent many hours assisting me with various hardware and software issues. Several members of the VRML/X3D community have assisted me. Miriam English (Australia) did a lot to teach me VRML. Clayton Cottingham (Canada) provided the communication between frames. Zlatomir Zarkov (Serbia and MonteNegro) also helped out with Javascript issues. Sergey Bederov (Russia) has been particularly helpful. In fact, he has produced some of the more memorable scenes. These include the morphing space surfaces (Euclidean, spherical and hyperbolic), the solar system and the atomic orbital simulations.

Various institutions have given permission to use photographs and/or code. The model for the Milky Way galaxy comes from NASA, Legacy Archive for Microwave Background Data Analysis. The schematic for the supercluster comes from the Group of Cosmology and Joint Chair of Cosmology Tartu University. I have made an attempt to seek permission from these people, but I have been unable to find any of them. I doubt that they would object, so I am presuming to do so. I have also had assistance from various academic consultants, Wendell Hill and Alan Migdall (University of Maryland), John Harshman (Field Museum of Natural History) and Andrew Hopkins (University of Sydney).
