Art Text is a narrow-purpose graphics and text-styling tool that's easy--and even fun--to use. This program is primarily intended for creating stylized buttons, logos, and blocks of text that you can then export (in a variety of file formats) to another program for creating a final product, whether a brochure or a Web page.
Art Text gives you an intuitive interface with a toolbar, preview area, and multilayer support that should be familiar to anyone who works with graphics programs, and the most recent version can also handle multitouch trackpad gestures. In addition to basic editing tools like flipping, blending, and rotation, you get a whole host of other effects including color and texture fill, linear and radial gradients, and shadow, glow, and metallic and materials options. You also get access to a ton of predefined templates, styles, textures, and vector icons and shapes. Art Text may be limited in its capabilities, but it offers a lot of different features to support its primary purpose.
