Open Source Projects

We build a lot of software in my group, and when time allows we try to open source as much as we can.  Since we have Github, most open source projects go on Github.  Here are some of the projects we have open sourced over the years.  Feel free to use them as you see fit, or even better contribute back your improvements!  We are always open to collaboration and sharing opportunities.
