+1 for Yin and Yang Theme
@gdigesu thank you for the nomination! 
Yin and Yang is a theme I created from scratch earlier this year. I actually built it by the request of my younger sister, who just started high school last semester. I’ve been helping her build a PKM system in Obsidian for her studies, including building a theme that would fit both of our design aesthetics. From this, I was able to create something that the both of us loved to take notes in. I then posted screenshots of this theme in the Obsidian Discord, and quickly received messages asking if I would release it publicly.
Since then, I’ve been receiving messages from many users about how this theme has helped them fall in love with Obsidian, migrate their notes to Obsidian, and push them into accepting Obsidian as their note-taking daily driver. I’ve also received lovely messages from non-English speaking users telling me that this is the theme they recommend to their friends (which is the sweetest thing ever)!
This theme has also helped in creating a friendship between me and my friend @mgmeyers . We have collaborated on making themes more accessible to non-English speakers (Y&Y update soon come!) and also getting custom icons supported in Obsidian themes (which was super time-consuming, yet totally worth it, as it been widely adopted by other amazing theme developers)!
The amount of positive feedback that I’ve gotten from this one CSS sheet just encourages me to continue sharing with this incredible community. I’m immensely appreciative of all the support this theme has garnered, and I’d love to close off this crazy year with a nomination for my theme! Cheers !
