This is a cube which actually looks completely different when I made it in openbrush VR. The purple part was actually a diamond mesh and the green "x" were neon tubes where some sort of light liquid flows through. The cube had rainbow edges and the dark grey thing is actually a "waving line". The sparks could light up but here on sketchfab it doesn't look that great. You can do everything you want with it except reuploading it.
