Great multiline stuff. Could be improved by using the actual U+2212 minus sign −, not - (U+002D HYPHEN-MINUS) when getting super pedantic. Did something like this last week making extensive use of unicode block 1D400 and different space widths. http://math.typeit.org/ helped as well.

Nice! That's like ASCII art but with more characters, like U+2320 TOP HALF INTEGRAL, U+23A8 LEFT CURLY BRACKET MIDDLE PIECE, etc.


That's pretty slick. Did you do that manually?

    ║ Yes.  All manually ║

Common lisp reader macros anyone?

    ⎛if ⎛> (+ a b)⎞ ⎛case x      ⎞ ⎛cond              ⎞⎞
    ⎜   ⎝  (- c d)⎠ ⎜    (1 'foo)⎟ ⎜  ((> y 2) 'quux) ⎟⎟
    ⎜               ⎜    (2 'bar)⎟ ⎝  (t       'error)⎠⎟
    ⎝              ⎝    (3 'baz)⎠                   ⎠

...(hmmm. For some reason that looks better in my editor than on the webpage. Apparently a fixed width font isn't necessarily fixed when it comes to unicode).
