Show Networks and Control Systems Pay What You Will Kindle Promotion!

This Friday and Saturday I'm running a special "pay what you will" promotion on the Kindle edition of my book, Show Networks and Control Systems.  To participate, just go to the kindle link for my book between midnight Pacific Standard Time February 22, 2013 and 11:59 PM Pacific Standard Time on February 23, 2013.  You should be able to get the kindle book there for free, and then use the Paypal button below to pay whatever you like.  The regular kindle price is $30. 

Thanks!
