Contrary to the large, orange spinner showing if you get a runtime error in the Simulator, the built-in one is almost invisible, and if you try to make it larger than half a fingernail, it becomes very blurry.
It’s a bit problematic to make image sheets manually, since Photoshop shrink-wraps the selection so that alignment is difficult and you can only check by playing the image sheet in Corona AFAIK.
Are there any GIF to image sheet converters, or do you have some general tips? Maybe you already have a neat, hires spinner to share?
