I was experimenting with Blender's material nodes and texture and accidentally created a (in my opinion, beautiful) stretched material by creating a small mesh and applying a large image texture. If it matters, I'm using Blender 2.82a.
How can I procedural generate this material using Cycle's material nodes?
I'm very inexperienced with Blender, so details would be appreciated.
