Hey Steve, I thought about doing it a while back, but from what I read you may have to let it cure for six months or so and I didn't want to wait ;)

I liked the idea of putting the concrete mix into plastic bags and squishing it into cool shapes and then let it harden up.

I have heard of some people putting cooked pasta into the mix so that you get lots of little holes and stuff when the pasta dissolves.
