I personally feel that Cheng's Change is a very magician-y thing to do. I'm learning it anyway because I like it, but I probably won't ever use it as a routined effect for spectators. Incidentally, to someone who asked previously, I feel that New Leaf (I hope you don't mind me giving a short opinion either Wallmott) is a very special sort of effect. Actually, it's my favourite effect in the entire set. Wallmott is correct, it's not something you'll do everyday, it's more a walk in the park and ok let me show you something to friends. But I feel it has so much potential as a really special effect. Firstly, it's a trick using nature. I think this in itself is inherently powerful; not just using props like cards or coins, but actually controlling the elements, controlling nature, feels to me, by nature, to be something deeper and more mysterious. When we speak of real magic we speak of surpassing death, superpowers, that sort of thing. Really, these sorts of things are, for the most part, extensions of nature - death being a part of the natural life cycle, superpowers such as flying or invisibility essentially harnessing the wind. So when an effect comes along that allows you to "commune" with nature, I feel that it has a lot of potential. The other thing that this trick has going for it is the very fact that it's not something you're going to approach a stranger with. Near where my girlfriend lives, we have several hidden forest paths that we regularly go for walks on. So you can imagine me performing this for her as we're walking along, alone, with nature around us. It's a really intimate picture, something that happens just for us, while we're alone, together, and in a place that happens to be quite special for us. I think magic of this sort is inherently beautiful; find the right time and place to perform New Leaf, and it'll be better than any you perform on the street to strangers.
