I've attached the code as requested.
We're sending the data in ASCII because we had issues sending it as raw data from Processing. When we sent a value from 128-160 the arduino mysteriously received a value of 63. All other values were fine. If we need to use larger values in the future, there will be less code to change and we won't have to worry about endianess.
