Fireflies Across the Border
Intermittently flashing, they carve free-flowing paths of light through dark time. Each spark signals an evanescent route of moving steps run-through by matching rhythms calling forth immanent reproduction. Leaving no trace except immediate direction to those already there, they are semaphores to an alternate world, passages from the future of a traveling autonomy.
The metaphor is derivative, a reproduction from a more articulate source. I cannot find the corresponding reference in the text I thought it was from.
