Open Illustrator and create some M&M's! To do this, use the pen tool and use points, lines and anchors to create half of the oval shape. Bert uses a green fill color. Photoshop does have 3D functions, but in this case, we will use Illustrator (Effect > 3D > Revolve). Make sure to turn on the preview setting so you can see the 3D shape. Use an offset of 0pt from "right edge" and the shape will look much like an M&M candy. Adjust the lighting as desired, then press OK.
