Reanimating Skeletons

Technically it's not reanimating, since they haven't been animated before, but I found this image online and my brother and I turned it into an animation! :D
There are 8 lines of 32 pictures each. Each line is a different direction (the first line is facing west, the second line is facing north-west, etc.) The first four of each line is the idle animation (for when the skeleton is standing around doing nothing). The next eight is the walking animation. So when the skeleton was walking south-east, we'd have to find the eight frames from [4,5] to [11,5] (where the first number is the column and the second is the row, but each column and row starts at zero, so that it's [4,5] for the fifth from the right and sixth from the top; the top left frame would be [0,0]). The end result was a skeleton which could be made to walk around with the arrow keys! :D
