I saw something along the lines of this vertical garden a few weeks ago on
Better Homes & Gardens, although I have to say that this version is much more interesting.
It did look reasonably easy to make (but then they often do on that show).

It is a vertical garden of easy-care succulents- great if you have limited space.
I really like succulents, and this is an unusual way of displaying them.

The one above looks like a living painting, and really complements the look of the bedroom.
