Solunars by Aldebaran Sidereal Academy

We used to generate these as a product at Astro Computing acter Neil got his graphic plotter-printer. We even did a book of them (probably still available if you search under Neil Michelsen). The Earth-Venus dance is particularly strikibg and beautiful.

Yes, I still have Neil's book with these geometric patterns. Very we see the heart pattern with the dance between Earth & Venus.

Aha, interesting.
Yes very true, Earth-Venus is amazing, like a Lotus flower unfolding

Or a valentine heart.
