I was thinking about including Mathematica as enlightenmentware. Mathematica 6 (https://www.wolfram.com/mathematica/newin6/ https://www.wolfram.com/mathematica/newin6/) was the first truly interactive system I used (we happen to have a box with a license at the university). It impressed me so much that I still have a lot of warm fuzzy feelings toward Stephen Wolfram and his work. Unfortunately, my relationship with Mathematica didn’t go anywhere: It was too expensive back then, and I never found a good use for it except for double-checking my homework. I tried other computer algebra systems, but they didn’t impress me as much. If you own a Mathematica license and found a good application for it, please let me know!
