SymmetryWorks is uniquely suited for creating symmetry-based stained glass designsjust set the tiling size to 1 x 1 to show a single tile. And you never have to worry about how your pieces of glass will fit together. The plug-in shows them as you draw, enabling you to adjust the shapes for a perfect fit. When finished, use Illustrator's gradients to simulate backlighting in a realistic mockup.
