I finally got around to updating the Featured Object in our themes in CAREO. The previous one had been there since October, and was waaay overdue to be changed.
The new Featured Object is the "Powers of 10" animation, done by Florida State University. VERY well done, and cool, too.
Oh, and through the power of hierarchically inherited themes, I only had to change 1 xml fragment, and all themes in our repository were automatically switched to the new Featured Object... Cool. We can override the default for any of the themes, if we want, but this works pretty well as is.
