This is a demonstration of using Crossbar.io to enable live synching of UI elements for collaboration.
Works across several tabs or browsers by setting a common controller
channel in all instances.
All interactions on this demo occur in response to messages routed through the instance of Crossbar.io displayed in the status line at the bottom of the demo box.
The demo uses Farbtastic color picker
created by Steven Wittens and licensed under GPL 2. The Farbtastic code was slightly
modified allowing to suppress color change events being generated when color is set externally
instead of by the user from within the control.
