Upside-Down Christmas Tree!

What would happen if you turned your Christmas tree upside-down? The upside-down tree needs less floor space, the ornaments hang away from the tree so you can actually see them, and best of all, there's more room for presents under the tree!

A very interesting concept - whether it's a 2005 fad or something that will actually last longer is yet to be seen, but it certainly made some companies extra money this year.

What every-day concept can you turn upside-down? What if instead of lamps and lights that shine down on us, we had floor lights that shine light up? What if instead of having the freezer over the fridge, we had the freezer on the bottom and the fridge section on top (I think I've seen an appliance like this already)?
