Would you mind sharing how you go about making these?

I found the Cahill projection a few years ago and was disappointed that I couldn't seem to find one in print.

The one I found that seem to resemble it is the Waterman projection which is also available in printed versions.

Spend a month or two reading the appropriate books about cartography, complex analysis, and approximation theory, and then write some Matlab code. :-)
