This element would turn into the first element it touches (that's not itself, of course).
If it touches several different types of elements at once, it picks one of them at random.
(Note that it doesn't constantly duplicate that element, like clone does -- it just turns itself directly into that element.)

I can't think of any good uses for it off the top of my head, but that's probably because I have a rather poor imagination.
(I'm sure others will be able to think of some good uses for it.)

I haven't decided on a name or color for it, yet. (that can be left to whoever may be willing to code it)

Considering some of the other element suggestions I've seen, I don't think this one is that bad...(but still, sorry if this suggestion is totally useless, if someone already suggested it and I somehow overlooked it, or if it can be done using some nifty trick I haven't heard of yet.)

What do you guys think?
