Polyform describes a community project whose outcomes incorporate a diverse mashup of local assets.  A community garden can incorporate seeds from local university agriculture programs, straw from local farmers, wood reclaimed from local structures and recycling programs for chicken coops and compost bins and local work training program participants hired for construction projects.

These projects don't involve complicated plans, just intentionality to the synergy of forms. We see the magic of acting local intersecting multi-sourcing.
