I have several friends who have become addicted to a game called Tetris
that is available on both PC clones and as an X client on Unix machines.
I'm feeling shamed that I can't offer them the same solution on the Mac.
Does anyone know of a PD version of Tetris available for the Mac? 

In case you don't know the name, but know the software, it's a game of
spacial orientation in which the machine drops shaped objects down from
the top of your screen, while you race to place them on the pattern of
objects that have accumulated across the bottom.  When you get a row
completed (i.e. filled all the way across the bottom), that row disappears,
allowing you more time to react to new object coming down.

Anyone heard of such a beast?
