Right now, each piece of paper in Dymanicland is a program. You put a piece of paper down and it "runs" - the metaphor breaks down at this point though. With a little bit of code, anything in Dynamicland can become "alive" and interactive.

For me, the impressive part of Dymanicland is how physical everything is. Want to see how something works? Find the paper that the code is printed on. Need help understanding some code? Bring somebody over to the wall, table, or couch where the code is. You can annotate the paper, draw diagrams on it, cut it, fold it, tear it, put it in a book to help others learn how it works. Want to edit some code? Point an "editor" token at the paper program you want to modify, then start changing the code.

Dynamicland isn't a room with a computer, it's a room that is a computer.
