Thanks for your kind words Normand.
I had a chance to watch some of your videos.
They sure are beautiful, I am going to attempt to make them asap. I really love the colour prisms they give off as you show in that one video, and it sure is amazing how they form into the pyramid like that.
Have you every tried growing one in a sort of mold like a dome or something? Maybe you can make a crystal skull this way.
Btw great music you do as well.
