Zen Magnets - Neodymium Magnetic Balls (@Varies)
These builds were derived using a truncated 12-ball triangle (tips of triangle removed).
Soccer ball Truncated Icosahedron (@240) formed from 20x truncated 12-ball triangles.
Triangle-Ring Subunit
(@012) - pinch 3xball sides together to form a 6xball triangle on inside, 6xball ring on outside
Convex Regular Icosahedron - formed from 20xTriangle-Ring subunits (using Triangle side to form 20xfaces)
(@240) - 5xTriangle-Rings top)+(5xTriangle-Rings top middle)+(5xTriangle-Rings bottom middle)+(5xTriangle-Rings bottom)
Extended Convex Regular Icosahedron (480) formed by adding/stacking additional Triangle-Ring Subunits on each Triangle-Rings aligned on each face Ring side to Ring side and Triangle side facing out.
At the Musée des Arts et Métiers, Paris. Lavoisier's laboratory is on display within the museum.

This also seems to be upright. There's not a major difference in images from nearby and afar like there was for concave mirrors
The crossed pair in 3D shows the virtual erect reflection of the surroundings to be inside the convex mirror, helped by the white dots - two on the beetle and the rest in the refection.
Convex Edge, Adjustable Set screw, Similar-Offset handle, Detachable finger rest.
Material: This scissors is and can be manufactured using two different types of Stainless Steel.
1- AISI-420 Japanese Stainless Steel. Rockwell HRC 54-56.
2- AISI-440C Stainless Steel. Rockwell HRC 58-60 two piece welded blade technology.
This is a selfie from awhile back (20 months actually from the date of posting...) that I forgot I had.
I remember taking this show (on the U of M campus, the medical center) because for as busy as that building is all the time, I am completely alone in this shot. All four hall, to the end of vision, were empty.
I also didn't really stop to take the picture. I slowed my stride, looked through the strangely quiet halls, looked up at the mirror, pulled the trigger, and walked on. I still can't believe it turned out at all.

The S-Compact Traffic Mirror is a frameless mirror that provides extremely high quality vision at an exceptionally low cost. Furthermore, it helps with the prevention of accidents and injuries. The mirror can easily be simply installed with 76mm diameter bracket supplied.

Simple plastic convex lens from the two dollar shop on a Cyclopital close-up stereo adaptor. Fuji W3 stereo camera.
Shows chromatic aberration at opposite edges of the stereo pair, as I expected. Is this bad enough to demand an achromatic magnifier at 40 times the cost?
Since I was using unusually shaped pans, I lined them with wax paper before baking - something about the batter's consistency made them rise up without "poofing" much, which meant these were concave underneath, like the lenses of my glasses or something.
Many concave and convex mirrors are just made from pieces of spheres upon which a reflective material has been coated. For such mirrors, an approximate focal length can be found by dividing the radius of the sphere by two.
These don't reflect rays far from the center of the mirror to the focal length exactly. This defect is called spherical aberration, and can be avoided by building a parabolic mirror. The headlights in cars are often inside parabolic reflectors so that all light is translated into wide parallel beams.
Spherical mirrors are often used for convex and concave mirrors because they're cheap to make.
The Hubble Space telescope had a blurry vision problem when first launched, because of aberration. Corrective optics had to be used to fix it
