Egyptian Pendulum Implementing Thoughts

A month or two ago I saw a post by @sanaRo about implementing thoughts, saw few people ask about that post but the post was deleted.

Something like “…working with the egyptian pendulum directly on the picture…”

I liked the idea and it got stuck in my head for a while now. Anybody wanna share the knowledge about this or there experiances?

It is something I am interested in as well but a real Egyptian pendulum is very difficult to get in my area. And the experts say that it is not for beginners. I would also like to hear about other members’ experiences :smiley:
