Thank you for visiting my website. Please note that it is currently under construction.

Please enjoy what content there is, but know that it may change or be re-organized at any point in the near future.

My previous website, which contains the cool scientific visualizations for which I am well known, is located at http://terpsichore.stsci.edu/~summers/. I plan to move content over from that site to here as I have time.

NOTE: The computer serving the "terpsichore" website crashed in Dec 2010. It is dead and I have not yet had time to revive the website. I was planning on migrating away from that machine, but not so suddenly!
