Invader Fractal

Invader Fractal in Mel version 1 Still some squares being left out, but all in all looking good. version 2 Complete, but need to add more size variations version 4 variation 1 Rewrote most of the space filling portion, and added frames etc. variation 2 variation 3 Based on Jared Tarbells Invader Fractal. except done in maya melscript. Below is the space filling portion of the script, using a main grid of 100x50 squares, we go through each one($j), if $j is white, j++, if not, search a random sized area for white squares, if a white square exists, we search random sized area - 1 for white squares and so on until random size = 1 and it must be black due to the first condition. If the random sized area have no white squares, we call the invader_plane()(not shown), which makes the invader plane at that area, and color that particular area white on the main_grid and continue(j++). There are two for loops within the main loop, L loop for going horizontal, which are increments of 50, and the K loop going vertical, which are increments of 1.
