Google celebrates Edison's birthday with a wonderful animated gif in which gears turn and the light illuminates. Go check it out.
I know a bit too much about Edison's shameless self promotion, shameless to the point where others were done down to achieve it, to celebrate him as wholeheartedly as I could. His behavior during the AC/DC war, his treatment of Nikola Tesla, his behavior toward Georges Méliès, and his film licensing monopoly which is why the motion picture industry moved to California are just a few examples. However, there is no denying the fact that he is an American icon.
The Google tribute is truly striking, no matter who inspired it.
