Doing a bit more research on Martha—she was a lecturer at Florida International University. Wayback of her themes page, which repeats the 300+ number and says they're only available on CD-ROM now (as of 2006): https://web.archive.org/web/20060502073323/http://www.gate.net/~royerm/index2.html https://web.archive.org/web/20060502073323/http://www.gate.n... Rate My Professor page (last review in 2011, seems a bit less enthusiastic than the earlier ones): https://www.ratemyprofessors.com/professor/554604 https://www.ratemyprofessors.com/professor/554604 FIU Math & Stats Dept. lists her as retired faculty: https://case.fiu.edu/mathstat/directory/retired-faculty/ https://case.fiu.edu/mathstat/directory/retired-faculty/ Perhaps you might consider reaching out to her and asking her for an updated collection. :) As for my obsession with NeXT themes, I think I'll stick with Scott Naness's work, although Leo Prieto's checkbox and radio button are definitely more authentic. (The original controls are simply too large to fit in the available space, but Scott is the only one to get the window frames right.)
