gwt-ns extends the Google Web Toolkit with a loosely associated group of modules, most of which wrap or enable new HTML5 or CSS3 features. The name originally had something to do with "non-standard" (referring to both the still nascent status of HTML5 and the not always universal support of feature fallbacks), but it's now kept mostly for its phonetic value.

Current Modules

• Canvas -- (yet another) GWT canvas wrapper. Uses excanvas as a slow but often usable IE fallback.

• GwtBox2d -- A "port" of the 2d physics library JBox2D, itself a port of Box2D.

• JSON -- A simple module for JSON serializing/deserializing. Wraps native or json2.js code, depending on browser support.

• TransformedElement -- A module to apply arbitrary 2d affine transforms to HTML elements on a page. Uses the new CSS3 transform property where available, the Matrix Filter in IE.

• Transforms -- A matrix module for representing and manipulating affine transformations. Includes 3x3 and 4x4 matrix implementations, as well as a wrapper for WebKit's preliminary version of CSSMatrix.

• WebWorker -- This module provides a framework for automatically compiling designated portions of a GWT project to native Web Worker scripts, which are then executed in parallel on supporting platforms. Also includes support for JSO message passing, worker emulation in older browsers (with no change in code), and full development-mode/debugging functionality.
