* Reading for Tuesday: Search Algorithms.
* Myra Cohen from UNL is visiting on Friday and will be giving a lunchtime talk (Free Pizza!).  I'll need to get a headcount in Wednesday's class.
* My son encourages you to stop by the gallery this week.

Project Questions:
* How do we get our drawings-as-values to show up on the same image as our turtley things?
  (1) Make the drawings-as-values the first thing you draw.
  (2) Draw on separate images and copy and paste.
  (3) Use the amazing (drawing-render! DRAWING IMAGE) procedure
* How do we copy and paste?
  (image-copy-selection IMAGE)
  (image-paste! IMAGE)
  * But that copies everything, including the white background.

Questions on the reading?
* Do the lab anyway
