Happy Pi day!

I know I'm kind of late here... but I think Pi day is worthy to celebrate even if a little late!

There are tons of nice resources to celebrate this famous number so I had hard time choosing, but finally decide to feature this link:

It includes Pi day Sudoku, pi trivia game, a link to an infographic, and an animation visualizing Pi.

Enjoy!
