Jonathan finished the first version of the code and we were able to test with a mouse.  The OpenMV cam does a great job in this application.  We are easily able to track mice in both light and dark (thanks to the onboard IR LEDs), and calculate X, Y, and speed in realtime.  Currently these are written to the screen, and to a log file on the SD card, but we are designing a shield for the OpenMV cam that will allow them to be recorded as voltage signals in near-real time.
