An interface that does something like put 52 cards,all visible, on one side and lets you grab and drag them wherever you want. It may sound weird because of what I'm leaving out (programmable robots, odds calculaters, or whatever). Just 52 cards that you can move around and set up any way you like. A more complicated program that includes this feature would be fine.
I lost my ancient version of turbo stud. Is there a downloadable version for sale?
