Announcing blank-canvas 0.4.0, a Haskell binding to the complete HTML5 Canvas
API.
blank-canvas allows Haskell users to write, in Haskell, interactive images onto
their web
browsers, via a specialized JavaScript DSL.
First Example:
{-# LANGUAGE OverloadedStrings #-}
module Main where
import Graphics.Blank -- import the blank canvas
main = blankCanvas 3000 $ \ context -> do -- start blank canvas on port 3000
send context $ do -- send commands to this specific context
moveTo(50,50)
lineTo(200,100)
lineWidth 10
strokeStyle "red"
stroke() -- this draws the ink into the canvas
There are around 50 examples on the blank-canvas wiki:

Enjoy!
