Popcorn.js enables you to do more with videos and sound on the web. Add interaction or tie events to certain parts in the video.
One very http://www.robmorrismusic.com/knowyourexit/“>nice example by Rob Morris binds in tweets in real time to match the lyrics of the song that is being sung. There are also claps pulled in via MechanicalTurk. Have a look.
Mozilla is also working on a tool to create these interactive experiences. So even the less technically inclined have a chance to breathe life into their creative visions. I think it can also work great for developers too since it will export the project to HTML5 code. That sounds like a quick way to bootstrap a project.
After a few demos and some background info the workshop went into a discussion mode. There were three groups split up into tech, learning, and media. A very nice idea. It really got discussions flowing in the right directions for the people in each group. Much better than mixing all these interests into one huge group.
I checked out the tech circle where Cole Gillespie gave some great insights and inspired a few ideas in me for a Popcorn.js project. The discussion was mostly around Popcorn.js specifics but also about device support for HTML5. Which was probably slightly out of scope but interesting still. I definitely got a lot out of it. (BTW if you see Cole here at rp:12, say hello; good people.)
