Barely plausible niche ideas. The outskirts and underpasses of a megalopolis. Burgeoning self awareness. The cultural fringe. Technologies that appear to be nothing more than toys. The fractal outline of a fern frond. Marginal returns. Emotions that are just barely ineffable. Border towns. The moment just before you lean in for a first kiss. Coastal ecosystems. Flirting with irony. The lucid dreamscape halfway between sleep and wakefulness.
The ragged edges of things are always the most interesting part.
