What base could I use to make a home made windchime?

I want to create my own windchime with some old pieces of materials I have discovered but don't know what sort of base to hang them from. I have found this picture (please look) http://i.ehow.com/images/a04/ec/49/wind-chime-recycled-objects-800X800.jpg and would like to find one of these to use as a base but I am not sure what this product used as this windchime's base is called and I don't know where I could get one from either. Plllllease help!! :)
