Now please be specific when asking questions. What about it do you want to make. The overall geometry? The construction? Are real world properties important or something that just looks like it? Do you even know what about the image you are trying to achieve?
First thoughts, search Minimal Surfaces and Mesh Relaxations. Plenty of examples of that around.
