Dragonfly on a Windpipe
Looks like a dragonfly crawling up the outside of a windpipe. It isn't.
The dragonfly is very real, the red thing is a sculpture in a remarkable garden near the Darmstadt Mathildenhöhe.
Have a look at this in full size.
The garden is part of a project in the southern German state of Hesse, Offene Gartenpforte, or "Open Garden Gate", where private individuals or organisations make their gardens accessible to the public. By chance, this sculpture is on the official website, but without the dragonfly.
