Cally has recently been inspired by a new Monkey finger yo-yo and asked me to update his design with a couple of changes.  I was more than happy to do so and while I was at it I thought I would post a couple of pictures of both Cally's and Jack's concepts.

Next time you see them make sure to tell them how awesome their designs are.
