Hi!
I saw that you guys would like to see some work by any hopeful interns, so I made an attempt at this exercise.  This is very similar to the reflections and translations exercise, but I think that's reasonable considering the similarity of the problems themselves.  Also, on my local server at least the equations sometimes take a very long time to load, though refreshing fixes it.  I'm not sure if that's my fault or my servers.

Anyways, I hope you have time to check this out, and maybe even my application too!

Thank you,
Kristina
