At an old employer, I wrote neat visualization that drew equal-potential curves through a sampled grid of points. Somewhat complicated, targeted for one specific feature. I leave, but stay in touch with friends there. They completely turned the ship and that whole module was no longer part of the system. A few years later, I get a message from a buddy: “dude, we dug up your equal-potential curves thing from SVN and damn is it nice to work with. Good job! That just saved me a ton of time!”
