A retired general vanished from his home. An unseasonably warm spring is making him harder to find

An experienced hiker and avid outdoorsman, William Neil McCasland isn’t the typical missing person, but the retired Air Force major general hasn’t been seen since he walked out of his Albuquerque home on the morning of February 27, leaving behind his phone, prescription glasses and wearable devices.

Experiments with Dürer-type tilings from a few years back.

@christianp i’m not sure if I can figure out how to write alt-text for them in a reasonable amount of time, but they are all radial tilings of pentagons based on a wedge of pentagons which are shifted in various ways.

Actually, the patterns are shown in pairs, the first in the pair has the pentagons coloured in partially transparent grey so that the overlapping of wedges can be seen, and the second is the same pattern in a solid colour.

The overall pattern seems the same in these four pictures even though they were obtained differently.

It's #TilingTuesday - Dragon rosette. Consists of 253 equilateral shapes tiled edge to edge without any gaps. It has 12 pentagons and a needle thin hexa star.

(1/?) Patterned Penrose Pentagon thread

I submitted this picture to the 2021 JMM Art Exhibition with the following description:

‘This year, Sir Roger Penrose won a Nobel Prize in physics for his work involving black holes. This piece is intended to be a general celebration of his work.

It consists of an impossible shape referred to as the Penrose Pentagon, which appears to be patterned with an Penrose rhombus tiling. In actuality, the tiling has been done over a large area, but is only visible through the strategically-aligned impossible shape, with shading providing the illusion of depth.

Last year the “shadow” of black hole at the center of galaxy M87 was “photographed” using the Event Horizon Telescope. Strangely enough, one can almost see a pentagon there. I have used a similar colour palette to tint this pentagon.’
