Pick a word of an object, for example a window. Use all letters of that word in your image and let the letters form the actual object. So for example, you see a wall and on that wall the letters window, these letters are not just letters, they are supposed to form the window. Now this is just one example.. perhaps you like better to use the word door, or house, or teacups and have a bunch of teacups in letter shapes... plenty of things to come up with.. .
