I do not get the impression from your message that you are planning to publish the idea. But even if you were, I would submit to you that acknowledging Mr. Tamariz' parallel work in this area is really all you would need to do to complete the ethics circle. You can perform any trick you conceive of, in your own way, and you should not stifle your own creativity by concerns over whether someone, anyone else may have thought of or done something similar. Over time you will realize there is nothing new under the sun. Your appreciation and where appropriate tribute to those who inspired you or have done similar work is the limit of your responsibility in most cases. Make every trick your own! At the same time, avoid becoming intoxicated with the illusion of originality, especially when it comes to card tricks. Be creative, be inventive, and enjoy!
