I originally found it here.
https://www.youtube.com/results?search_query=cosmic+cloud+painting Then I bought some paints and started learning. What I learned was the dilution of the paints with the Extender is not critical at all. roughly 50/50 is a good starting point. I also leaned that itt shows up really well on black, barely at all on light maple. This can be a godsend if your not good at keeping the paint within the line. There have been some fun new experiments online that I've found. One is instead of blowing it around use a balloon to sort of smear it. Very cool patterns. Gonna try that later this week if I get time. Using wood burning tools to create the black areas was magical when I found that. You can see that technique in the angels. Masking off areas similar to what you would do with an air brush also opened a whole new thing for me. see the mirror that I call Faux Abilone.
