Could easily be made with hollow box uprights, run the water tube through one and the top hollow box with a PVC tube that you drill holes in for the water to run out. Faux paint it to look like copper, really pretty easy.
DIY: hypertufa pots - what a brilliant idea. As a new and enthusiastic clueless gardener, I bet I'm going to need 42 gazillion pots to cover 2.5 acres in tossed-out failed garden projects. What better way to get them from start to dead than their own pretty tufa pot :)
