This is a program for martial arts pratictioners (or anyone else) who can't practice with a live partner as often as they'd like. VDM lets you create drills for whatever you want to practice, be it a martial art, the French language, or even your times tables. Use images, sounds, and text to turn your PC into 'martial arts flashcards' that you must respond appropriately to. Take the monontony and predictabiltity out of your workouts with VDM.
