Have you ever considered landscaping with glass bottles? We typically have some glass wine/water (ok - mostly WINE!) bottles for recycling and I'm learning that some people love to "recycle" these into their gardens in borders.
In fact, I even came across a site with how to instructions!
I also stumbled upon The Casual Gardener blog with photos and more instructions:

I'm really digging the cobalt blue wine boarder. I can see this in the front garden at LaNa!
