another batman function is found as a stationary solution of the non-linear 4th order extended Fisher-Kolmogorov equation: u_t + 10^-8 u_xxxx = 10e^-4 gamma u_xx + u - u^3 which describes the propagation of domain walls in liquid crystals batman-ears: http://www.matmol.org/images/images/kolmo.png http://www.matmol.org/images/images/kolmo.png
