* Go over the new project code.

* To do in the project code today:
  + Make the moving lego "bounce" when it runs into other legos.

* Notes:
  + Lego faces are a single polygon, so specular reflection, shading, etc.
    are not very detailed.  Could make them look nicer by breaking those
    faces up into many polygons.
  + slowness parameter
  + textures
  + changed config file format
  + point and click
  + hpp versus cpp files
