If you invent some effect and plan to publish it, you should first search other method and variations of that effect. So, Daniel Madison 's duty was to be familiar with Sankey's effects. And then, if the method is different enough to be published, other originators should be mentioned. So, if Madison independently invented his effects, he still should mention Sankey. And if idea is from someone else, original inventor should be at least credited.
I can't understand what is so great in Daniel Madison that he should be protected in this case.
But, our information is limited, so we cannot judge for sure.
If I were playing around with something and I claim originatly to it but I wanted to make sure it was original, I would have to do some research, right? That's just it, it is so fregin' difficult to try to find anything specific in magic seeing how well the secrets are guarded. I would literally have to buy dozens of books, dvds, materials, etc, to figure out whether someone invented something BEFORE ME or not. I can't just google it up!
I believe I came up with an original handling of the DL (I am not speaking hypothetically) and I claim it to have invented because my creation process was not swayed by ANYTHING; it was completely legit (of course, no one will believe me).
I am soooooo not up-to-date with magic (isn't that apparent?) . I only heard of this Daniel Madison fellow a few months ago when I discovered sites like T11. I just buy books and materials and just study from then. I'm so wrapped up in my own material I don't eve bother reading about other magicians and their bio's and whatever.
However, these are intellectual properties and not one magician can claim ownership or patent a certain movement, idea, etc. But he could claim that he found it FIRST and by doing that would make him look like the actual "creator" of that idea as, claiming you have invented something someone else invented FIRST wouldn't make you look very creative, or ethical. It would coincidental. But coincidences HAPPEN. Just not as often as you'd expect from the magic community.
Another person can claim he found that exact same idea (gesture, ....Whatever) too as long as he's being legit about it. But he can't claim that he's the only founder because the guy the other professional magician on the internet already claimed it before he did. So, yah. You invented something but someone already did it before you so, claiming that you discovered it without this in mind will make yo look VERY unethical and everyone magician would probably shun you from their community.
It's like someone claiming they've invented an effect exactly (or similar to) Indecent right when Indecent is published by W:H.
What IS UNETHICAL is to create something awfully similar to Jay's magic with him (and his material in mind) and claim it as his own. That's unethical.
Oh well. Daniel removed the forgery-material from his website so...
However, I did think that extremely bogus, "I'm a visual artist..." cop-off was extremely lame. I mean, seriously, it says "illusionist" and "cardist" on his website. Isn't illusionist just a fancy term for magician?
