A place to sit at

Based on my experience sitting on a roof is usually a great experience - a totally new view on something you already know.
This set could allow you to enjoy such an experience more often. Provided, you are not afraid of falling down :-).
Actually, I wish I had something like this on the roof of our cottage.
P.S. This is what I like on art - making you aware of some opportunities and dimensions of world you are not aware of or not being brave enough to realize them.
