FontStruct is a free font-building tool brought to you by the world's leading retailer of digital type, FontShop.
FontStruct lets you quickly and easily create fonts constructed out of geometrical shapes, which are arranged in a grid pattern, like tiles or bricks.
You create 'FontStructions' using the 'FontStructor' font editor.
Once you're done building, FontStruct generates high-quality TrueType fonts, ready to use in any Mac or Windows application.
