In this excellent tutorial at VectorTuts, you’ll learn how to easily create 3D springs in Adobe Illustrator using little more than a simple shape and the 3D Revolve Effect. The finished results look complex and time consuming, but the actual technique really isn’t at all. You may not have cause to create a spring in the near future, but the technique is quite handy to learn – you never know when you can apply it to something else you’re working on.
