 * This playground requires the new playground format and features released in Xcode 6.3. This version requires Yosemite.
 * I will be updating it to whatever Apple releases at WWDC
 * From time to time playgrounds can crash or seem to disappear from time to time. The current fix suggested by Apple is to show the package contents of the playground and delete the workspace.
-* Type the word "turtle" in the playground. You should see "Turtle" on the right. Mouse over it and you will see the quick look icon and the value history. Click on the value history. You should see a rectangle with a turtle's head (>) in the middle.
+* Type  "turtle.view" (this is a change I'm not happy with and will work to fix) in the playground. You should see "Turtle" on the right. Mouse over it and you will see the quick look icon and the value history. Click on the value history. You should see a rectangle with a turtle's head (>) in the middle.
 * Make the turtle move by typing in "forward()". Make the turtle turn by typing in "right()".
 * Create routines and your own functions.
 * I've removed the custom operators for forward and back. They were cute and fun but not good pedagogy. You can add them back.
