Haha, I remember reading through your paper "A fast and well-conditioned 
spectral method" last year and feeling like my head was spinning 
afterwards. I vaguely recall that it views differential equations in 
GegenbauerC space, a basis choice which has a bunch of super convenient 
properties, all of which I have completely forgotten by now.
