Please don't think I'm criticizing on your choice of monetization. Making money to continue doing what you like is a pretty big cornerstone here at HN :)

I was more curious what you were charging for.

Also, you're being discussed over on https://www.reddit.com/r/occult/comments/3esa6n/drawable_alt...

You really hit it with triangles / sigils and the occult. Perhaps a pivot? Too small a market?
