haha. yes. I actually use a different method. but still, yes.
I just a kind of seed called 決明子 or cassia torae. (so-called ‘wise decision’ seeds. They’re also good for eyesight (i.e., liver function). Oh, I should tag @raphael. I think they’re boiled and combined with other ingredients.
Anyway, for Yijing use, you focus on your question and just dip into a bowl of the seeds and pull them out between 1st and 3rd finger. Odd number of seeds is a yang line. Even number of seeds is a yin line. Then one more dip to show which line of the situation is primary. Long ago, I started using a Mancala game board since they’re perfectly suited to the purpose.
