I think the the mercator or sinusoidal projection is a = good start when adding new projection types. Btw, the math map gimp plugin seems to be a nice way to experiment with ne= w projections and parametric image warping in general. http://www.complang.tuwien.ac.at/~schani/mathmap/ Some very nice examples at: http://www.flickr.com/photos/sbprzd/ ciao Pablo =5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F=5F= =5F=5F=5F=5F "Ein Herz f=FCr Kinder" - Ihre Spende hilft!
