Thanks to Jim Adams for this update :)
It seems that we have the final word of where the flash presentation began. Clifton Farr of WindowsPro.net kindly let him know that he was the person who originally placed OfficeNGO.swf on the web. It came to him through a survey apparently conducted by Microsoft through surveysavvy.com. This presentation and relevant screen shots have been present on his site since March 22nd. Credit where credit"s deserved and Clifton was obviously here first. His site is worth a look, and there is even a download to the original flash with apparently no ill will from Microsoft (go figure?).
It"s nice to know that people able to discover where the animation originated and that it is in fact part of a Microsoft market research tool/survey.
I like to think that Neowin, and our very own Mr. Magoo helped to publicise the news as well.
