If you want to shape your rock into whatever shapes your desire, you can smear the rock mixture around small diameter PVC pipes to get something like Tonga rock-like branches. Plus, if you drill PVC pipes beforehand, you can connect the PVC-rock via zip ties. You can use whatever materials you want to make the frames, as long as they are relatively saltwater-safe. Plastics, acrylic, etc. The possibilities are endless!
