For Displaying the Unknown:
if its neutral it can work. if you don't stand and say this is evidence that proves such and such. if you can present what you've seen and let the audience make their mind up on their own, without your influence. if the blank canvas can be the painting and each viewer, a participant who adds on it what they will. your job should thus be to open a window and say, "look! look, I saw this; please take a moment to look for yourself as I did." you won't demand a discussion or praise for your discovery (if it could even be considered a discovery). your only hope is to share that sense of the unexplained, even if only temporarily unexplained. to remember that still, there are much ordinary mysteries hidden in plain view where no one ever bothers to look anymore. at most a neutral agreement, an accordance that we, together as well as separate can certainly say, we're not one hundred percent sure of what's going on here.
