"Spool" A spool is a small pool and spa conbined. It can be used for cooling off in the heat of summer and made hot on a cool evening. Great for parties! This one has a waterfall, landscaping, a paver patio and a gas fire pit. See the whole story at http://www.deckandpatio.com/DP_Blog/?p=1105
What a charming way to fill a blank wall in the garden! Could rely on the gutter for occasional water sound, or pipe it for continuous water flow....I'd paint each one a different color. No not rainbow colors, though that might be interesting.
