Forgive me for not sharing your enthusiasm.
I don't believe - in the final analysis that there is a substitute for studying yoga in a live setting.
You will miss too many pointers. The animations are not well done in terms of the relationship between the breathing and the posture. It could be fixed, but why not just show a quicktime of someone doing a correct posture?
You'd have to charge for that I suppose while you can justify giving away something this cryptic. I prefer the photos of the cat strectch to the animations in all honesty, because it is a real person.
I started doing yoga from a book. Take this small piece of advice from me, and listen to Gurdjieff: sometimes you'll get more if you pay for it, and you'll work harder. It helps to study with someone who is directly connected to the aural tradition, and if you shop around a bit in what Choggyam Trungpa called the Spiritual Market Place. Be careful how you make your decision and choose a yoga teacher the way you would choose a doctor or dentist!
In fact I may offer some free quicktimes including some more advanced postures, and I'm not certain whether giving them away would be a good thing. Even when I was charging, I would occasionally teach someone who would not pay attention and come to me accusing me of hurting them by suggesting they do a particular posture or exercise.
For them, I'd suggest they lie down if they have the urge to exercise, and wait until it passes.
Namaste, and always read the discaimer before trying a posture at home that you see in a book or on the web. It's your spine, and they are your chakras. Take good care of them!
