Post your conceptual idea that could win the Turner Prize

This year it was the shed that was dismantled and turned into a boat which was dismantled and turned back into a shed. A few years ago we had the light being switched on and off in an empty gallery space. These are fantabulous works of art, but I'm sure that the minds of ILX can come up with something at least as good.

OK, body fluid is always a good one (pissing in the snow, canning your own shit, a cast of your head in your own frozen blood etc). So here's my idea: I will buy masses of very expensive creams, moisurisers, anti-ageing, ant-cellulite products, empty them and fill them with my own ejaculate, then set them all up in a gallery space made out to look just like a beauty counter at Selfridges, complete with sales girls. The curator can write up some blurb about how the work interrogates the matrix of normative sex and capitalised bla bla bla.
