TI-83+ Graph: Batman

I've been having fun with my TI-83+ graphing calculator lately, and I thought I'd put up some of the art graphs I've done.

This is a parametric graph. So for those of you who have the calc and would like to give it a try, the equations are as follows:

X1 = {1, -1}(2.5sin(.5T) + 4)
Y1 = .7T + 2

X2 = {1, -1}(7sin(.5T) + 4)
Y2 = 1.8T - 1.5π

X3 = {1, -1}(cos(.5T) + 1)
Y3 = 2sin(.5T) - .1T2 - 3

X4 = {1, -1}(.25T + 2)
Y4 = .5T-1 + 2

X5 = .6T - .6π
Y5 = .75sin(.5T) + 5

X6 = {1, -1}(1.4cos(.6T) - 3.4)
Y6 = 1.7sin(.6T) - 3
