The thing I love about Disruptathon is the voting power it gives the audience through iPod Touch devices. Attendees can also download the Disruptathon app from the iTunes AppStore on their own devices.
A partial video of the event is below (battery died about 70% of the way through - sorry). A more professional video will be uploaded shortly, and I'll link to it here when it's up.
Video is ~56 minutes long and may take up to 30 seconds to start playing.
