On github I made a fork of Brian Whites Scribble Game and added a Colors to his perl script and made it more graphical... I wouldnt call it a GUI though.

is a fork of Brian Whites Scribble that merely adds color. Test it out.
Not sure I remember that well myself. It was an extension of some anagram games I played with Mom while home for Christmas one year, mostly done to see if I could. I haven't touched it in around 10 years.
