Reflection on Data Visualization
* Good parts?
  * How computers recognize images
  * Made me more interested in the GIMP than when I thought it
    was evil.
  * Made me realize that I could write battleship
  * Interesting to do the data manipulation
* Bad parts?
  * The Escape key
  * Need to be easier to pick up in the middle (lots of nods)
  * It's been too long since we've programmed in the GIMP
* Vs. Excel?
  * More "behind the scenes" knowledge
  * "No Limits" ("No Limits" is a registered trademark of Grinnell College)
  * But a lot harder
