PhiMatrix is a design and analysis software application for Windows and Mac. This is the demo version. The PhiMatrix grid system overlays any image in any software on your screen to identify or apply phi proportions in various grid styles, as well as custom ratios. It's not a plug-in but a universal overlay, so you can use it with PhotoShop, Illustrator, InDesign, Picassa or any other art program.
