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

A convexed mirror mounted on a graffiti covered wall. The reflection shows a small empty parking lot and a second mirror.
Playing with the Hemesh and Convex Hull by Lee Byrons library. Starting Point is the Hemesh Voronoi example. The voronoi cells are subdivided and then slices of the vertices are sent to the convex hull algorithm.
They are abviously inspired by jtnimoys awesome work for the tron movie.
