I had the pleasure of checking out the JSon systen last year and really enjoyed tying with the realistic materials. Claes is a master at turning the materials into realistic creations, and not only are they deadly fishing flies, they also stand up to some abuse.
If you have heard the name Graham Owen then you will know about the realistic flies he produces. He is the hollywood fly tyer, having flies appear in episodes of Breaking Bad, Pushing Daisies and Law & Order to name a few as well as movies and more. A while back I had seen mention of his images being used to push an anti-evolution agenda, and being published in the Atlas of Creation. Not just one, but 3 of his flies were used without permission for this propaganda.
Several of my fly tying photos were published in the Atlas of Creation, without my knowledge, and presented as purportedly real living creatures, to be compared with fossilized specimens, to disprove the theory of evolution.
