Yes, it's Pi Day, 3-14, the funnest of all the various goofy geeky holidays! (Well, May 4 -- Star Wars Day -- is right up there.)
I posted the earlier material to hold this space until I had my own material ready to go. I didn't properly observe Pi Day last year, so I wasn't going to make the same mistake twice!
(These photos have been modified with an app called Prisma that makes nifty "artistic" images out of source photos.)
Happy Pi Day, everyone!!!!!
