[math-fun] Illustrating Mathematics

I'll be attending an ICERM workshop on "Illustrating Mathematics" next week (https://icerm.brown.edu/topical_workshops/tw16-1-im/), though I'm not sure its aims match my needs. In writing articles and essays I spend a lot of not-very-enjoyable time handcrafting illustrations using tikz when I'd rather be using something more interactive and wysiwyg. (Anyone remember a drafting program from the 1980s called idraw, not to be confused with a newer and more famous program by that name? I still miss it.) Sometimes I use pictex, or Mathematica, but it's always a chore. Do any of you use mathematical drawing software that you actually find fun? Jim Propp
