FYI, Peter Dalgaard's original posting from 2004 that I used is here: http://tolstoy.newcastle.edu.au/R/help/04/06/1094.html
Per his suggestion, I changed the smoothing parameter to be: "pnmsmooth -size 1 1" instead of "pnmsmooth -size 5 5" which he originally described. The new graphic is here: http://www.broad.mit.edu/~finnyk/Rhome2.jpg It is predictably, less smoothed, and does look a bit nicer. Tim Churches' version also looks very good. As someone else has noted, Tim's does have a few rough edges involving mostly margins (I had to manually tweak them). I also manually put the 45 in to make it look like the original. I'd be happy if either his or mine replaced the current version, if there is consensus.
