"Fabric.js is a framework that makes it easy to work with HTML5 canvas element. It is an interactive object model on top of canvas element. It is also an SVG-to-canvas (and canvas-to-SVG) parser.

Using Fabric.js, you can create and populate objects on canvas; objects like simple geometrical shapes — rectangles, circles, ellipses, polygons, or more complex shapes consisting of hundreds or thousands of simple paths. You can then scale, move, and rotate these objects with the mouse; modify their properties — color, transparency, z-index, etc. You can also manipulate these objects altogether — grouping them with a simple mouse selection.

You can add text on canvas and dynamically manipulate its size, alignment, fontfamily and other properties. You can apply filters to images, making them grayscale or removing background. You can serialize the entire canvas into a JSON string — saving it locally or on a server — then completely restore it at any time. You can also export canvas data back into SVG at any time."

"Metric & Calibre are a pair of typefaces that share a fundamental geometry yet differ in the finish of key letterforms. Metric is a geometric humanist, sired by West Berlin street signs. Calibre is a geometric neo-grotesque, inspired by the rationality of Aldo Novarese's seldom seen Recta. They were conceived as a pair but function independently of each other."

"Geometry of Design - the first book in our new Design Briefs Series - takes a close look at a broad range of twentieth-century examples of design, architecture, and illustration (from the Barcelona chair to the Musica Viva poster, from the Braun handblender to the Conico kettle), revealing underlying geometric structures in their compositions. Explanations and techniques of visual analysis make the inherent mathematical relationships evident and a must-have for anyone involved in graphic arts. The book focuses not only on the classic systems of proportioning, such as the golden section and root rectangles, but also on less well known proportioning systems such as the Fibonacci Series. Through detailed diagrams these geometric systems are brought to life giving an effective insight into the design process."
