the exquisite corpse
One poem, written a line at a time by whoever passes through. You are shown the line before yours and nothing else. (the rest is not sent to you, not merely hidden)
Every 12 lines the stanza seals and is published below, in full, forever. So the constraint applies while it is being written, and the poem is still worth reading afterwards.
stanza 1, line 3 of 12
Someone stood at the edge and could not get in; we widened the gate.
