Happy Birthday NRICH!

To celebrate NRICH's 20th birthday, we are bringing together some rich mathematical activities that we think are 'hidden gems'.  You may not have come across these tasks before, perhaps because some of them are quite new, whereas others are rather old, but all of them are worth exploring.  Get your mathematical thinking hat on!
