Das Saarpolygon in Ensdorf (Saar) ist ein Denkmal zur Erinnerung an den im Juni 2012 endgültig beendeten Steinkohlebergbau im Saarrevier.
Das Saarpolygon steht auf der Bergehalde Duhamel in Ensdorf, der Bergehalde des Bergwerks Saar. Diese Halde mit einer Grundfläche von rund 50 Hektar erhebt sich rund 150 Meter über das umliegende Saartal. Auf Grund der exponierten Lage ist das Polygon weithin aus allen Himmelsrichtungen sichtbar.
Das begehbare Denkmal ist rund 30 Meter hoch. Zu dem rund 35 Meter überspannenden Querstück führen von beiden Seiten genau 132 Stufen in 25 Meter Höhe. Die Aussichtsplattform wiegt rund 60 Tonnen. (Wikipedia)

The Comma is a fascinating butterfly. The scalloped edges and cryptic colouring of the wings conceal hibernating adults amongst dead leaves, while the larvae, flecked with brown and white markings, bear close resemblance to bird droppings.
The species has a flexible life cycle, which allows it to capitalize on favourable weather conditions. However, the most remarkable feature of the Comma has been its severe decline in the twentieth century and subsequent comeback. It is now widespread in southern Britain and its range is expanding northwards. butterfly-conservation .org
What the opposing angles fail to realize is nothing would be possible without the holding foundation.
A Polygon derives from the greek word meaning many sides and is considered to be an unbounded sequence, or circuit of alternating segments (sides) and angles (corners).
The modern mathematical understanding of a Polygon is to describe this structural sequence in terms of an 'abstract' polygon which is a partially-ordered set (a poset) of elements.
The interior body of the Polygon is an entirely other element; and for complicated technical reasons so is the null polytope or nullitope - but that is for another future series.

This twelve sided barn was built in Mystic Quebec, Canada, by Alexander Wallbridge in 1892. Suspended from the top of the barn's conical ceiling, the original mechanism for rotating a large turntable in the centre of the barn is still in place. The turntable, much like the railroad turntables of days gone by, enabled fully laden wagons to enter the barn and to be rotated to the appropriate storage bay, where they would then be unloaded. The building is now a museum.
Like many Commas, the Gray Comma is best identified with the ventral view which in its case is a cryptic charcoal gray pattern and accounts for the common name. They are very difficult to find when perched on a tree trunk or like this one, gathering nutrients from wet, muddy places. There is a striking difference when they open their wings to present the dorsal view which I also posted this evening and looks like the dorsal view of many of the Comma species.

As it dries, clay shrinks. Tearing along the edges makes cracks that join neighboring cracks, creating polygons. Other cracks stop before joining, like punctuation marks.
These mud cracks on the Mojave Desert playa have a white surface. The cracks reveal underlying brown tones. The photo was taken from standing height.
The resulting pattern might be a good model for floor tiles.

Yes, I know a polygon has all straight sides, but I couldn’t think of a song called ‘Rounded Rectangle Window’!
