Yoga on My Wii Fitness Board

I am having difficult time making it to the fitness center to do classes in yoga.  There are only two classes a day and I am either commuting to work or at work most of the time.  But, I discovered a yoga program on my Wii fitness.  It makes use of the Wii fitness board to detect balance and shifts in balance.  There is a tutorial for each pose and you select a "trainer" to lead you through the exercises.  During a variety of poses, I have to stay within a yellow circle and follow the breathing.  It is not adapted for floor mat poses but does give instruction for positions and breathing.  I wish that there were more programs like this to use at home.
