The overall idea is to create images and videos with reflections of several
visually similar objects with labels distinguishing among them and their
reflections (with reflections labeled by path of reflection). It's an experiment
in machine learning.

I like the trace idea, seems like it will work. It sounds like I can just write
all the data generated in the tracing process to an ascii file and I'm set.
Thanks a lot.
