Charcoal idea

Experimentation with sellotape and charcoal.
This actually works far better than I thought. The visibility of the tape is still an issue and would be noticed on the white floor but the reflections would make it illegible until it became dirty with charcoal. I wet some of the paper to account for people with wet footwear and this gave a nice effect, the overall look is subtle because the white takes quite well to the charcoal I think it is the change in material and texture that would make the text stand out.
I tested this on A4 paper because I did not have a white floor or any light coloured floor.

IDEALLY>>> this installation would be as I described in an earlier post, red POSITIVE lettering on the floor with the other text written in some sort of adhesive. The source of the charcoal would be a BBQ stye mound of burnt stuff in the centre of the room, made to look like a sort of camp fire used for cooking but without untensils around to make link it closely with the cooking of meat. There would be burnt pieces of blackness scattered throughout the room to ensure that people walked through it and dragged it about the place to reveal the text.

The whole problem with this method, as with the other sellotape dirt one is that the people that first enter the installation will get the best experience. After the text is revealed it's a bit of a one liner, more like an interactive performance. The artwork would be finished in a sense because the making process, the unearthing of this amazingly thoughtful beautiful spectacular subliminal sarcastic sellotape message is the main focus of the work.
