Geometry of null polygons in full N = 4 superspace.

We discuss various formulations of null polygons in full, nonchiral J\T = 4 superspace in terms of spacetime, spinor, and twistor variables. We also note that null polygons are necessarily fat along fermionic directions, a curious fact which is compensated by suitable equivalence relations in physical theories on this superspace.
