Cody's problems aren't over yet. The overhead projector was sort of an odd unit - the light source came from above, and was reflected by a mirror below the slides. The unfortunate side effect is that all of Cody's slides - although printed in color - turned out in black and white on the screen! The ink was too thick for two passes of light, and so all the colors in the slides block all light, appearing black. Poor Cody.

Note that Dan Weld and Oren Etzioni (to Dan's left) are in the front row on the far side of the room.
