I'm in.  I work mostly with Divine magic, if you are interested in my system.

As for an experiment, I am not sure what would be appropriate.  But I want to do something.

I have a slightly different version to suggest. Does anyone have a knife that they carry frequently or at all times?

I do.

So the pocket knife has special attachment or emotional value for you?

I'm down with using Obs' knife. My suggestion is this. The owner of the knife places it somewhere and avoids contact with it for 2 weeks. They do not look at it, do not touch it, nothing. In that time, the rest of us will choose a single direction ("positive" or "negative" to oversimplify). We project only in that way on the knife, using our will, our emotions, whatever our mode of choice may be. The objective is simple: make the object noticeably different to someone who is familiar with it. If we're going positive, the object is to make it better. Sharper, cleaner, shinier, it doesn't matter. If the owner believes it is better than when it was left alone, we have succeeded. Likewise for negative.

It sounds subjective because it is. We're not turning the sun green or making somebody weightless. We are changing what one person perceives. And subjective is the name of the game there. How does that sound to everyone?

Marael, are you wanting to be added to the list?

Sounds really cool.  I am down with this.
