Young eavesdropper Zack sent me http://mathcircle.berkeley.edu/archivedocs/2009_2010/lectures/0910lecturespd... a weird proof based on (X,Y) = (log(sin(x+y)/sin(x)), log(sin(x+y)/sin(y)) being (to me, remarkably) area-preserving. I think the paper needs a picture of this. gosper.org/passare3.png --rwg Unfortunately, the paper perpetuates the old, unslick proof that Harmonic#(oo) = oo.
