Yellow Duckling on the roof of Children's Discovery Museum of San Jose.
The sculpture on the roof keeps on changing. While the current (May 2011) street view shows this yellow duckling, earlier imagery of Feb 2011 showed a White Rabbit (probably of Alice in Wonderland fame) and even an earlier Street view imagery of 2008 showed a Pink Dog. The current 45 Degree aerial view of Google Maps shows a monkey (probably Curious George).
