Ok I don't want to start an argument with anyone here but I feel I should say something as Kremsam was PM'ing me about it, and he should agree with what Im going to say about this after chatting to me privately about it. Before I start and people come back asking question's about me, if anyone has read any of my post's on other subjects you should know that I am a massive book fan and have quite a large collection of books, and other reading materials and sources after doing magic for 15 years. I'm not saying I know everything because I don't but I have a fairly good knowledge behind me.
Kremsam should agree with what I'm about to say and shouldn't get upset as we have spoken about this in private. I agree that his change does look very similar to other changes out there, and there are other methods besides this where the same can be achieved and I sighted a couple of sources for his reference. I gave him my thoughts about how I thought it was done and then he told me his method (which I wont say here). As I have said before there are other published ways to achieve what his change does, but to my knowledge I don't know of a method that is the same or similar to the one he is using. Again I don't know or think I know everything there is to know, and I could be proved wrong about this.
