Joey's Tangle Challenge #12: EZ as Pie

This one is for Joey's Challenge #10 by madebyjoey.  Her topic is EZ as Pie, using only tangles that begin with E or Z, and including a pie if you want.  I went in a somewhat tangential direction and used the sign for Pi as my string.  I used the tangles euca, zooyz, zin and zanzee.
