Irregular Pentagons Truncated Icosahedron 30 units
I always consider it a compromise to fold kusudamas out of paper other than squares, but this just doesn't work well with squares, so I compromised, because I love this simple visual effect of this model. I wonder if anyone has done something similar to this?
Designed by me, I think.
Folded out of uncut rectangles of memo paper, proportioned 1:sqrt3, I believe.

Self Interwoven Irregular Hexakaidecagon 1
Several people have mentioned that it is helpful to have a picture of a single frame to help explain some of these self-interwoven polygonal structures.
In this picture, the frame is distorted so that the polar 4-fold axes are as far away from each other as possible. This is the exact same frame as the second picture next to it(picture 2) , but in terms of design, it is closer related to the first compound I made with these frames.
Stone wall texture. From the first floor of the Egyptian Governor's residence at Canaanite-era Aphek in modern Israel.
just a design on a yellow background to begin with...
thanks for looking...appreciated....best bigger.....hope you have a Great Weekend
Irregular Heptagons and Pentagons Tessellation, designed by me.
Front-view
Hi! I was just doing pleat combinations on test papers, and suddenly, this came up. The pleats are just Byriah's 8-4 Tilling molecule and 90 degrees pleats. I wasn't too excited with the pentagons that made this look like Eric Gjerde's 5-4 Tessellation with heptagons on it, so, next time I'll make a tilling of "just heptagons", if I'm lucky enough. :) The back side is good enough, but I won't do a photo of it. :)
Used ~9" square of kami paper, 32x32 square grid
Four Interlocking Irregular Hyperboloidal Omnitruncated Digonal Dihedra 48 units
In my hand.
In this view, you can see how small the model actually is.
This model was a spinoff design I generated on POVray as a variation. Despite the creative name I gave it, it is essentailly of compound of 4 irregular cubes. The model is very easy to weave, but somewhat difficult to assemble, especially at the small size I made it at. (I'm really running out of room for new big models.) If you are wondering abou the hyperboloidal, it is because the faces are not planar, and would have a concave warp if they were solid.
Designed by me.
Folded out of copy paper.

An irregular Planetary Nebula roughly 2600 light years from us in the southern constellation of Musca.
Taken with an 11" Schmidt-Cassegrain telescope pushed to a focal length of 4.8 metres at f20. The 3.2 megapixel camera covers a field of only 10 x 6 arcminutes. Around a third of the width of the full moon across the frame, and the width of nebula, less than half that again...
This RGB composite was created from 4.1 hours of Hydrogen-alpha exposures and 50 minutes each of Red, Green and Blue. 6 hours and 36 minutes in total.
A stone wall at 579 Trinity Street (south-west corner of Trinity St and East 6th St).
I photographed this from the curb. People were walking along the sidewalk and kept hesitating before walking between my camera and the wall. I told them to carry on. Everyone should just keep moving if someone is using a digital camera.

Finally, done! It's been 270 units and over 20 hours of work, but I finally have a perfect model.
