Hi, I knew someone had posted something awhile ago like this, but it took me a few hours to remember it. :-) So check out Tk Rubberband Demo. If you combine it with Crian' GED, you would just about have it. If you don't want to deal with ps, you could use the Tk::WinPhoto module Tk Screen and Canvas Screenshots to output png, and use png2gd to save as gd.
