It's wind and the rocks are volcanic. I've been to other dry lakes and seen the tracks and the rocks. It is not exclusive to Ractrack Playa. I've seen these "wandering rocks" on Ivanpah, Silver, and El Mirage Dry lakes.
When the playa gets wet, it turns into a sludge that serves as a lubricant. Since the rocks are light and the winds strong, they move. They only leave tracks when conditions are right. I've also seen rocks that just have a bit of mud dried all around them.
There are already a few companies making artificail blood in the US. One is Biopure. All of them are waiting either for the completion of clinical trials or FDA approval. The Biopure product has already been approved in other countries.
