Recently, after graduating with a EE degree from the University of Colorado Colorado Springs and working at X-IO for a few months, I found myself out of a job. This gave me plenty of time to work on projects! (Update: I have a full-time position now!)
I realized that it might be nice to have business cards. The problem with normal (paper) business cards is that once I got hired they would all be obsolete. The solution: use epaper to have a business card you can program with new information at any time!
