There's a good anecdote about Feynman and his sense of play in Danny Hillis's keynote for the 2000 Game Developer's Conference (video at http://www.gdcvault.com/play/1014862/2000-GDC-Keynote-Dr-Dan...). At 10:50 he talks about asking a physics question with respect to why dry spaghetti shatters a certain way, and what that led to.
There are also some other good stories in that talk, one about Marvin Minsky which immediately follows the Feynman story. The whole thing is worth listening to, I think.
