GE's tag line is "imagination at work." To underscore their offering of "imagination" GE provides a free tool for collaborative drawing called Imagination Cubed http://www.imaginationcubed.com/
Imagination Cubed is an application in which three people can draw on the same whiteboard at the same time. This tool can be used for business or it can be used for fun, or both. I'd like to see if we can use it in a Social Web Associates meeting and blog about it.
