The Halema'Uma'U crater as seen from the Jaggar Lookout at Hawaii Volcanoes National Park. This was taken in late April, just before the eruption on the Big Island. The park ranger told me that the crater was the most active it had been in two years that evening.
Triangle vs circle. While the kids are playing we adults get also to play. But I seriously doubt that my daughter was thinking about polygons in this case. :)
Much different from the ventral view on my first post.

Amsterdam - Spaarndammerdijk.
Ventilation towers of the Spaarndammer car tunnel.
Designed by: Tjep.
The stainless steel towers consist of folded surfaces with a pattern that is inspired by leaf veins.
In opdracht van de gemeente Amsterdam heeft Tjep. vier torens ontworpen die de ventilatieopeningen van de nieuwe Spaarndammertunnel vormen. De 6 meter hoge roestvrij stalen torens bestaan uit gevouwen vlakken met een patroon dat is geïnspireerd op bladernerven. (architectenweb.nl)

RWE - Tower in Essen. Architects Ingenhoven, Overdiek, Kahlen und Partner.
A polygon with 51 corners and 32 m in diameter. The building is ecologically orientaded, the double-glas facade allows a natural airconditioning and it wins natural energy from daylight and sun saved by energy-storing materials. The planners won several awards for this.

This was taken with a 40 year old Canon FD lens (with a E to FD Mount): 50mm f/1.8. There is a lot of dust in the lens which only appears with a very small aperture around f/22.

The Gray Comma is found from Alaska to Newfoundland in the north, south in the Appalahian Mountains to North Carolina, and from Kansas west to Wyoming and Colorado. In Alberta, the Gray Comma occurs throughout forested regions and is usually associated with mixed wood forests. They are sighted frequently along roads and in clearings. (Alberta Butterflies)

Recently, I participated in the Macphun architecture photography contest and submitted this and another picture, which where both showcased on their homepage, but unfortunately I didn't win anything. Some of you might know this picture since I already uploaded it, but for the contest I did a slightly less extreme edit and hence I decided to reupload it. Hope you like it!
PS: Sorry for my absence the last weeks, but since people know that I'm singing and playing the guitar I had a lot to do with practicing songs and singing them at christmas concerts :) Hope that I'll find more time for photography soon.
One of the most common forms of patterned ground in Arctic regions are ice wedge polygons. In winter the cold causes frozen soil to shrink, and cracks form (similar to drying mud). In spring meltwater seeps down into the cracks. It freezes and expands when it is chilled by the still-frozen soil. The frozen water forms wedges of ice in the soil. The ice wedges tend to increase in size year after year. I found these patterns by chance flying a drone over tundra. It is much harder to observe these polygons from ground level.
