The Last HOPE conference, now being held in New York City, is as much for people interested in hacking the real world as it is for computer techies.
One such real world presentation on Friday was called "Undoing Complexity--From Paper Clips to Ball Point Pens." Despite the title, it was about hacking high-security electronic locks from Medeco. (The paper clip in the title is a reference to using one as a way of bypassing one type of security in Medeco locks.) The presentation was very well attended, SRO in a large room.
