Google unveiled on Friday its first Google Doodle to feature HTML5, the next generation of Web standard HTML programming, allowing developers to create pages with rich multimedia content.

This Google Doodle replaced the company logo with an interactive mobile to honor what would have been American sculptor and artist Alexander Calder’s 113^th birthday, featuring a hanging sculpture that users can press and hold to turn.

In a post on the Official Google Blog, Software Engineer Jered Wierzbicki wrote how he was inspired to create a doodle for Calder and his creations after visiting the Museum of Contemporary Art in Chicago.

Resembling an abstract fish, the logo had movable sections linked with each other through single wire strands.

In Wierzbicki’s own words, “This is Google’s first doodle made entirely using HTML 5 canvas, so you need to use a modern browser to interact with it. It runs a physics simulation on the mobile’s geometry, and then does realtime 3D rendering with vector graphics. Only recently have browsers advanced to the point where this is possible.”
