i dont know about turbo Prolog but if there is XPCE for it u can use graphics.
I use SWI-Prolog where XPCE is integrated. XPCE is a package for object orientated programmin in Prolog. It comes with many defined objects e.g graphicals, windows, dialogs, textitems and all teh stuff u need.
I did a prolog procejt for offered by the University of Hamburg where we tried to make a clone of teh famous Unix Bubbles game. It is an animated game where u shoot coloured bubbles to a virtual roof and build lines. Its like Tetris.
Anyways its all possible with Prolog if u have XPCE (and easy to use)
