70x70 spritesheet of 20 frames. Use for 64x64 icons (or 70:64 relatively to icon, if rescaled).

There's is preview with transparency, but it'll probably look bad, so I also included preview on black background.

I also included animated gif preview, but I have no experience with gifs, so it can look like a crap.

It's "inspired" by Warcraft III's autocast icon animation (I tried to mimic it).

This animation was made in 3D and then rendered into 2D spritesheet.

I recommend to use fast frame speed to to make it look good.
