The relationality of all experience contains challenges to our understanding of organizations that we have 
barely begun to come to terms with. I can illustrate this by extending the metaphor of the blind men and 
the elephant. In its conventional telling, each blind man had a grip on a different part of the beast, and 
they were unable to agree on what it was really, really like, that is, as one of Kuhn's "fixed and neutral 
experiences." But there is more, for the elephant isn't just standing there but instead ambles through the 
forest and the veldt. The blind men are trying to understand the system as it evolves and as their experience
of it unfolds. The blind man clinging to a leg experiences an elliptical forward motion. He who has the 
misfortune to have hold of the tail is jerked and whipped about in a random fashion. A few feet forward, his 
colleague, in the crotch, is periodically flooded and/or pasted with output that seems to have nothing to do 
with the beast's motion or with the feel of the sur

I want to use a single gradle+intellij project to build, run, and test multiple arbitrary binaries created from a single repo and source tree. Some notes:

1) A typical example is the robot world project I'm doing for We Think Code. I want one tree, and I want to use it to build/run/test two clients, a service, and a making app.

2) By "one source tree" I mean one .../src/... hierarchy, with main/test/resources below it. Intellij handles this well. Multiple trees are harder to both organize and navigate.

3) I know how to use sub-projects with source dependencies. I don't care for them. Intellij's gradle runs are already slower than their native ones, and when you throw in multiple sub-projects for each run, they get even slower.

A classic "switch on type" in Java. The draw method interrogates its parameter's class, and decides what to do as a resuilt.

interfact Thing { }

class Wall implemnts Thing { }

class Door implements Thing { }

class Chest implements Thing { }
