This is where I am now heading after talking with a few people I am now sure exactly where I am heading. This will be a full life sized person posed in the kneeling position being bound by chains. This will be constructed out of timber rods, then have a material skin so it can be filled with stuffing so it has a human build and is able to stand alone without support.
I am still deciding whether to include maps so you get the sense of it being chained to a postcode.
