For my main menu idea with the large rotating objects, I thought it would be good to create a save/load type icon in the form of a floppy disk. I will be keeping with the flat polygon no texture style for the game.
I got an image of a floppy disk and used it as a template to work out how to model it, adding edge loops where I thought they would be needed on key details.
I then moved vertexes into a rough shape and began extruding in to create the detail.
