Cultural, thus sub-cultural, constructions are spawned in many different ways.  Take the Mathematical sub-culture.  It exists across many Cultures (per se) by giving the various participants a commonality and binding them with a communicatory medium, e.g, formulae.

She believed in nothing; only her skepticism kept her from being an atheist. -- Jean-Paul Sartre

travelling to other 'cultures', i was always struck more by how they were all based on doing their best to first survive their environments, then try to make that survival into a thing of grace.

underlying every culture that has existed (formality of occurring!), there is a substrate of potential relationship, because cultures are all built on the past, and the future is partly our to define, especially culturally, (and preferably politically too, but that's another yarn to spin).

i might not like kalahari bushman food, ot understand their language of clicking sounds, that remind me of dolphins, buti can relate through facial expression, laughter, gesticulation etc.

mime works like this.

so, culture as invisible superstrings of interlaced mycelium crisscrossing under the humus of daily interactions and interconnections, with the mushrooms of actual cultural emergence popping out quite unpredictably, vigorously and with great swiftness, dying often just as swiftly.

i guess this is leading back to memetics...
