Here you will find collection of great public sources of samples and demos coming as result of multiple years of close collaboration with industry, academia, consultants, and more. Just mention few Sanford Friedenthal, Lenny Delligatti, JPL NASA, NASA, Orbilta ATK  (NGC), Sierra Nevada Corporation, LMCO.  

We all know list is much longer, so please add more into the comments.
