When worlds overlap: Google fetes John Venn



 
 
A playful interactive doodle served as Google's tribute to mathematician John Venn on his 180th birth anniversary on Monday.
 
Visitors to Google's homepage (www.google.com) were greeted with an animated Google logo, with a button resembling a Venn diagram inviting them to click on it.
 
Clicking on the diagram starts an interactive game based on the famous Venn diagram, which uses circles to "visually and logically sort groups to illustrate their relationships to each other."
 
"For example, one circle may contain things that are mammals. The other circle may contain things that have wings. The overlapping space that both circles occupy would consist of mammals that have wings," doodle lead designer Mike Dutton explained.
 
Dutton said he and his team had quite a brainstorming session until they decided to base the doodle on "sound logic and silliness."
 
"My favorite that I worked on would probably have to be the kraken. I loved the idea of taking something that is utterly terrifying, such as a large sea creature that devours entire ships, and turning it into just a little dude having a bit of fun, albeit still at the expense of the ship and its crew. As long the diagram checked out logically, it was fun to take liberties in the final reveals," he said.
 
He thanked astronaut retired Canadian astronaut Chris Hadfield for "being gracious enough to allow us to draw and animate him." — Joel Locsin/TJD, GMA News
