Rocks have less “funny looking” characteristics to them as just a rock sample since rocks are just amalgamations of the minerals they are composed of. There are some funny looking minerals that will look the same anywhere, but rocks will only normally look funny based on their weathering or formation.
That being said, I think pillow basalt formations look pretty funny!

They’re formed by lava immediately contacting water so it forms into a ball because the outermost layer immediately solidifies. It’s kind of like piping out macarons or icing, but you are applying constant pressure to the piping bag, can’t stop, and can only move around the tray you are piping them onto
