Map projections, oblique case

I came across this geo site after see the fascinating map projection in the CIA FactBook:

“Geography, sir, is ruinous in its effects on the lower classes. Reading, writing, and arithmetic are comparatively safe, but geography invariably leads to revolution.”

(1879 testimony before a Select Committee of the House of Commons, London, England, regarding expenditures of the London School Board)

Fun with map projections – oblique case
