I did most of the Earth API work for an educational application called StrataLogica: http://www.stratalogica.com/ http://www.stratalogica.com/ This marketing video of theirs has some examples of the stuff we did with the Earth API: https://www.youtube.com/watch?v=Jl2HWhPEpIU https://www.youtube.com/watch?v=Jl2HWhPEpIU One very frustrating thing was that several of the interactive tools I built duplicated features that were available in the Earth desktop client but won't exposed through the API: line drawing, image placement, etc. But it was clear even back then in 2009-2010 that the Earth API wasn't getting much attention within Google - rare updates with few new features added - it felt very much like somebody's 20% project. So we didn't wait for Google to add those features but built them from scratch.
