What projection appeared in the NYTimes this morning?

Question

enter image description here

Perhaps not as GIS related as some, but definitely about maps. Can anyone identify the map projection that appeared in the New York Times this morning? It's not one I've seen before, and a quick scan through Map Projections: A Working Manual did not yield the result I was looking for.

There's a little bit of discussion on the Cahill-Keyes projection at http://gis.stackexchange.com/questions/1775/discontinous-or-interrupted-map-projections — matt wilkie, Dec 06 '11 at 23:05

It appears to be the Cahill-Keyes modified version of the Waterman Butterfly projection (see the Gene Keyes source at the bottom of the image). More info: http://www.genekeyes.com/ and here: http://www.cartotalk.com/index.php?showtopic=7360

Yes, it reminded me of the butterfly but not quite. – mattwigway Dec 06 '11 at 21:18

More precisely, Cahill-Keyes is a modified version of B.J.S. Cahill's 1909 Butterfly World Map. Mine was first devised in 1975, with early hand-drawn b&w prototypes printed in 1979-84. The Beta-1 digital version appeared this year. Steve Waterman independently designed an octahedral Cahill-like map on different precepts than mine in 1996, and has published wall-size versions in color; see my friendly detailed critique of the Waterman Map.
