I linked to it on my work blog as part of my attempt to summarize this year 's SXSWi . It is a hopeful sign of the potential of my country that this year this prize is shared by two people who trace their respective political ideals to opposing poles on our national political spectrum . for some reason i think this will happen a lot this year . The first 100 mouse lines will be sent to these centers this year , and more will be added in the future . Special guests this year include Sandip Burman , a professional percussionist specializing in North Indian tabla drums , the West Lafayette High School Percussion Ensemble under the direction of Matt Conaway and Ritchie Brickler , a xylophone player from McCutcheon High School .
