If you write small programs that interact with other programs, then rearranging them on the floor/table becomes a form of programming (similar to how combining UNIX-style programs in shell scripts is a high-level form of programming).

So even when playing just with the papers, you can be programming.

There's also the interplay of arranging papers, and live-editing the code in a particular piece of paper. In Dynamicland, the projector highlights printed code in green/red to visualize diffs.

You can sketch a UI element on the paper (eg a rectangle and token for a numerical slider), then go back to code the interactivity. Units in the code are inches on the table. Subtle things like that break you free from the laptop.

When you want to "commit" your code changes, you print a new version.
