Optix is one of the most clever and fantastic ideas for an effect / gimmick I have seen in a LONG time.
I am a worker, and am grateful to be able to perform 3 to 5 times per week.
I received Optix only two days ago, and still have a lot of practicing to do. The concept, the instructions and the gimmick are superb.
The only thing I'd recommend is replacing the loop that comes with the gimmick with your own, as the one that came with it doesn't behave the same way it looks like it does for Tobias in the video. This may be due to my lack of practice compared to his, <>
Point is, take this beautiful thing - make it your own. Don't be afraid to take it apart, tweak it and customize it so that it works best for you.
Also, I absolutely wouldn't recommend this for beginners as the misdirection and psychology involved to pull-off the effect shown in the trailer is "easy" as long as you have the chops and experience.
Overall, huge thanks to Tobias (and Team E) for sharing this with our community. Anytime I can add something to my arsenal that involves using a spectator's belongings, it immediately adds to the perception that they have just experienced REAL MAGIC, not just a magic trick, and as far as I'm concerned that's something I strive for everytime I perform.
Looking forward to becoming better at this, so I can do it justice and create the punch it deserves.
