Some of us are intrigued but can't pay a visit to the lab in person. I would love to see some videos that illustrate what you're describing and better understand how they would eventually synthesize into real life productivity
In a sense, it's basically just a framework with a text editor that isn't based in an OS but instead a 2d surface that you interact with, using your hands and interacting in a more social medium than something like, say, git.
While those uses are certainly easy to see and imagine in Dynamicland, the mission statement for Dynamicland is to "incubate a humane dynamic medium whose full power is accessible to all people."
The researchers at Dynamicland take this mission statement quite seriously and are making a new medium. Like any medium, this one isn't explicitly limited to one kind of use.
