Personal computing is currently riding the wave of possibilities opened up by 3D printing — the ability to turn a design into an artifact.  No need for a machinist and machine shop, just a tricked-out printer and stack of glue sticks.

It is possible to make the legal system a resource for the programmer.  If you generate the form that would have a particular legal effect if approved, signed, sealed, delivered, filed or otherwise acted on by someone or some succession of someones, and those persons do click, stamp or file … then you have inflected legal reality.  You can do this in the system.  Or you can chain printing systems, using 2D printing to enable the stamp or file and await a click confirmation that it has occurred.  If keep track of results, the system will be come to be able to predict which print runs will be successful and which ones tend to jam.
