More information about what the site does would be helpful. Also, I get this error on Firefox/Windows "no video with supported format and mime type found"

Edit: also click on the demo and saw the simulator but couldn't get it to do anything. What is supposed to happen in the simulator? Should I be able to click on something? Any instructions/information would be helpful. Right now you're assuming everyone knows what the site is about and what the simulator is supposed to do.
