Draw a bendy path, click a button and  - it’s a limb.  Or take three circles and two art layers, click the same button and again - it's a limb, with perfectly rotating joints. For raster layers you can use either method - no need to move anchor points or parent anything.  Limber 2 does it all: Vector art, raster art, bendy paths, puppet-pins, faux-3D tapers and over 100 presets in the Limb Library.
