I'm the Trigonographer at trigonography.com, where I'm spotlighting my various "proofs without words" for trigonometric identities and relations.
I'm also the Hedronometer at hedronometry.com, compiling information about the dimensionally-enhanced trigonometry of tetrahedra. (Currently, the link directs to the Hedronometry section of my blog.)
I occasionally post to my research and mathematical miscellany blog, "The Bloog!".
