The entropy of the three-charge NS5-F1-P black hole in Type IIA string theory comes from breaking $N_1$ F1 strings into $N_1 N_5$ little strings, which become independent momentum carriers. In M theory, correspond to strips M2 brane that connect pairs parallel M5 branes separated along M-theory direction. We show if one takes account backreaction on obtains a maze-like structure, can add waves....
