Google is celebrating the 113th birthday of sculptor Alexander Calder (Wikipedia article) with an interesting Google Doodle on the main search homepage. Conveniently, it is a digital take on one of Calder’s famous mobile sculptures and interactive, too: You can rotate it around in three dimensions by pointing your mouse at one of the edges until the pointer changes to the drag handle.
The digital sculpture reacts differently depending on which piece of it you “grab” to rotate the whole thing. Notice how it also casts a realistic shadow below the search box, in real-time. Calder is well-known for the Cirque Calder, a miniature sculpture of a working circus he created to fit inside a suitcase. He went later on to perfect the art of mobile sculpting using common materials such as wire, string, pull toys and more.
