Diamond Tessellation

here is a cool math art sculpture I made in Rhino-cad (no grasshopper or plugins)

its based on one shape, a minimal surface of a tetrahedron spun and rotated, rinse repeat. this was part of an exploration to create a nice looking gyroid I could use for more complex boolean stuff, but this one fairs quite well also!

UPDATE:
after research i've found I've stumbled across something very similar to a triply periodic minimal surface (tpms), but not exactly. the closest one I could find
