MC Texture Generator v1.2.0 - Gear support!
Although the code for this release is not really up to my standards, it should at least be accurate to how the gears were originally generated. To get the clockwise animation of the gear, simply reverse the order of the frames, starting from the first frame of the counter-clockwise animation.
Gear trivia: the gear animation is updated every in-game tick (20 times a second, or every 0.05 seconds). As the gear animation has 64 frames, it takes 3.2 seconds for one full rotation of a gear, meaning that the gear has a RPM of 18.75.

The same, at a higher frame rate, but slightly slower because GIF files can't support the right playback speed
To generate the higher resolution / frame rate versions, you'll need to change the code yourself at the moment. I'd advise checking to make sure that these are accurate, as they were generated when I was still working on the gear rotation code. The cutoff at the sides seems to be intentional.
