After last year where while being super efficient, it was just impossible to see it all in one day, I took a 2 day pass this year, and spent 10 hours on saturday and most of sunday. This allowed me to attend/enjoy a fair amount of talks while seeing all the exhibits and even chat with some long lost friends :)
There were all kinds of makers, from costumes, burning man machines, talks from famous people (from mythbusters' Adam Savage, to Arduino Creators from Italy, and the creator of the longest flying paper airplane).
A really cool construction where bikes that you could use to play tron:

Mythbusters' Adam Savage, gave us a good speech again. Well worth attending.
