Composite Equal Area Projections
Of course the combining technique also works with most polycylindric and pseudo-cylindric projections, including those of Craster, Eckert, Boggs, etc. and with my hyperelliptical system of projections. Affine transformations can yield more variants.
These are of little value but fun. The ones demonstrated include the Lambert cylindrical, Carl Mollweide’s projection, and the sinusoidal.
