The simplest of the four Spatial Poems that were designed and published by Maciunas as Fluxus editions, A FluxAtlas is an accordion-folded map documenting the directions in which the participants in the event were facing at a specified moment on a particular day.
For each spatial poem, (this is #2) Shiomi would mail invitations to potential participants asking them to perform an action or event, and send her the documentation.
Reprint of Spatial Poem # 2 originally published in 1966.
