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.

Aquest és el campanar de l'antiga catedral de Sent Liser. Aquest estil constructiu és molt caracteristic del romanic del entorn tolosà.
La vila de Sent Líser (Saint Lizier en francès) es troba en un puig sobre el riu Salat, just al nord de St. Girons. Té la particularitat de comptar amb no una, sino DUES ex-catedrals. Aquesta és una de les dues, l'altra es troba al cim del nucli antic, i s'anomena N. D. de la Sède. Una cosa molt complicada de legalisme canonic medieval. Sembla que va tenir un sol bisbe però amb dos capitols catedralicis separats. En fi.

=============================================
A view of the romanesque bell-tower of the former cathedral of St. Lizier. This style of tower is quite usual in the Garonne basin.
Saint Lizier (Sent Líser in occitan) is nice old village above the Salat river. It has the really unusual detail of having TWO former cathedrals. I can't really understand what happened, but it seems that in the middle ages it was the seat of a bishop, but with two cathedrals, and all was abolished during the French Revolution. The other (former) cathedral is known as N. D. de-la-Sède.
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)
The Saar Polygon in Ensdorf, Saarland is a monument commemorating the coal mining industry in Saarland, which ended in June 2012.
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.
Ce joli papillon nous est apparu et nous pensions qu'il avait les ailes brisées, mais non il a les ailes dentelées. Je ne mis connaît pas, mais d'après des connaisseurs, il semble que ce soit un polygone virgule.
Tous les polygones sont difficiles à identifier, en particulier les individus aux ailes usées qui volent au printemps.
New photography gallery open in North Vancouver called the The Polygon Gallery. Foggy morning the day I visited.

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.
This is from Badwater at Death Valley National Park. A manual blend of two exposures.

Blue hour shot of the Shard taken from the public viewing platform above the Thames Path near to London Bridge.
I spent so much time concentrating on this shot that I was completely oblivious to the illuminated Tower Bridge lifting to let a tall ship pass.
Thanks goes to James Beard, who made me aware of this great little viewing platform through his photostream.
