Parallel Parking optimization (US customary units)
In my brief moment of semi-fame, my exploration of parallel parking ended up in the New York Times 10th Annual Year In Ideas magazine http://www.nytimes.com/interactive/2010/12/19/magazine/ideas2010.html#Perfect_Parallel_Parking.
Shortly after there was a front page article in the local New Orleans Times-Picayune http://www.nola.com/education/index.ssf/2011/01/offbeat_lusher_charter_school.html
I certainly have to credit Professor Simon Blackburn, University of London, for his original work which sparked my interest in the subject.

Even though Geogebra was never mentioned by name in any of the news articles, it was central to my being able to visualize the problem better and test/confirm my equations.
This Geogebra model is in US customary units. I've also posted a metric model at http://www.geogebratube.org/material/show/id/3023
