How cool is this?  A family bought a home with a rundown pool and converted it into THIS:

Garden Pool started as one family’s blog to document converting an old backyard swimming pool in to a closed-loop food-producing urban greenhouse and has evolved in to a non-profit organization.

The GP (short for Garden Pool) was a one of a kind creation invented by Dennis McClung in October of 2009. It is truly a miniature self-sufficient ecosystem. Rather than keeping our creation to ourselves, we have decided to share it with others. Garden Pools are being built all over the world offering an easy and sustainable solution to current food production challenges.

What a great use of space. I love it.
