Here's a heart-shaped polyhedron I made from paper using Stella4D, along with the spiky base below. Used these for a teaser video for my last single.
Hmm, can't embed YouTube shorts, but here's the link and a screenshot: https://www.youtube.com/shorts/pCrfCjQrrbY

Also used the heart for the cover art.

Here's the full song if anyone's interested. It's my longest and biggest production!
