Here is the "logo" I made for the talk, which outlines the geometry of the systems we're studying. This shows dark spots rotating in/out of view as the star rotates, and a transiting exoplanet that zips past more frequently than the rotation period. This does not represent an actual star/planet system, but is simply instructive:

Finally, a movie that demonstrates the finer detail features that we see during exoplanet transits, allowing us to break interesting degeneracies in determining the spot properties:

For the curious, tools I'm using to make these:
- Python - to compute model light curves
- IDL - to render frames to .eps (could be done w/ Python)
- ImageMagik - to convert frames to .jpeg or .gif
- gifsicle - to create animated gif's
- ffmpeg - to create .mp4 movies
If you'd like to use any of these animations in your presentations, please include a note that gives attribution to me!
