blank-canvas-0.5: HTML5 Canvas Graphics Library

blank-canvas is a Haskell binding to the complete HTML5 Canvas API. blank-canvas allows Haskell users to write, in Haskell, interactive images onto their web browsers. blank-canvas gives the user a single full-window canvas, and provides many well-documented functions for rendering images.
