Proper credit and attribution will be included here shortly. For the moment, we wish to take a moment to thank USGS for their worldwide earthquake information. Enormous thanks to NASA for their fascinating (and high quality) moon & earth images, 3D texture maps and API. And the USNO (Naval Observatory) for providing planetary maps and earth / sun / moon relationship data. Fascinating stuff!
