This third installment of the Ritz Cracker Problem adds a bit of advice as to where you could go in terms of solving some of the problems posed by Episode II.
Keep in mind that while I provide the 2-D rendering of the problem, this is very much still a 3-D problem. My goal in showing the 2-D representation was to give the student an avenue to travel in the event they were stuck.
If there are any other questions that you can think of other than the 3 questions posed in the video, then post them in the comments. Be creative!
