This is similar to Pivot Animator, or a 2d blender ripoff. Move the pivot points to adjust the stickman's pose. Set the "Show Pivot Points?" slider to 0 to hide the points, and 1 to show the points. Note - You can't adjust points while they are hidden.
this could be made with clones i might expiriment with that (probably not) i might also fix the fact that you can pose any point anywhere
