In 1995, shortly after the 3'd Tcl/Tk Workshop, held in Toronto, TclTutor was released on an unsuspecting populace. Since then, there have been over a million of downloads, 3 major rewrites of the GUI, a translation into Portuguese, a rework into a web tutorial, 2 books, a movie and a TV game show. OK, no TV game show, and I haven't made the movie yet, but...
The GUI framework has been used for several proof-of-concept tutorials including Java and Perl, as well as several Tcl extensions.
The paper will discuss what was done right and wrong
