Interesting design Jon. Have seen a wrench similar that used roller bearings in a similar manor, just can't remember where. Like Frank says, not sure how well it will hold up or what limitations it will have for use but a good concept, ripe for refinement. More that I like the site. Hadn't been there before nor seen it in any of my Adobe forum/emails. Found it a treasure trove of creativity and Adobe Based. Thanks for the link...I'll spend some time there when I can.
