Here’s what I’ll say to answer the questions so far:
I would say it can be done surrounded. Could it be done surrounded by YOU guy? No. But by laypeople, I think it can. The secret moment happens so quickly that I doubt it could be seen by people who are looking where they are supposed to look. This said, it’s probably most visually appealing head on. Luckily, I have a feeling most people on here rarely perform these in surrounded conditions

I would be willing to bet you only performer for one or two people at a time because of the intimacy of the pieces.
As for examinability, I’ve handed it out every time I’ve performed it and no one has found anything. If you want to be extra “safe” you can hand it all out before you perform the trick. But I would say yes, it’s absolutely examinable.
Also! This is in the description, but some people may have missed it: the steel ball version actually includes a bonus handeling which cannot be done with the die version. I thought about including it in the demo, but ultimately decided it would make for a nice suprise when you find out what it is.
