CSC151 2007S, Class 31: Randomized (Unpredictable) Drawings

Admin:
* I hope you had a great break.
* My mother is giving a talk during class time today, and I thought that 
  I should attend.  Dr. Davis will teach.  I'll be back tomorrow.
* Reading for tomorrow: Geometric Art
* Assignment 12 is ready, and is due Friday.  
  It requires a bit more preliminary work than some previous assignments, 
  so I'd recommend that you start soon.
* A few of you requested that we go over husk-and-kernel programming.  
  We'll review the topic on Friday, as part of our discussion of 
  local kernels.

Overview:
* Why use randomness.
* The random procedure.
* Random art.
