FreeCAD will be a general purpose 3D CAD modeler. The development is completely Open Source (GPL & LGPL License). FreeCAD is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties.

FreeCAD features tools similar to Catia, SolidWorks or Solid Edge, and therefore also falls into the category of MCAD, PLM, CAx and CAE. It will be a feature based parametric modeler with a modular software architecture which makes it easy to provide additional functionality without modifying the core system.

Rotates images and is gpl – so perhaps good fodder.

Context Free, but written in JS and canvas.

Processing.js is an open programming language for people who want to program images, animation, and interactions for the web without using Flash or Java applets. Processing.js uses Javascript to draw shapes and manipulate images on the HTML5 Canvas element. The code is light-weight, simple to learn and makes an ideal tool for visualizing data, creating user-interfaces and developing web-based games.

Processing.js runs in FireFox, Safari, Opera, Chrome and will also work with Internet Explorer, using Explorer Canvas.

The Processing language was created by Ben Fry and Casey Reas. It evolved from ideas explored in the Aesthetics and Computation Group at the MIT Media Lab and was originally intended to be used in a Java run-time environment. In the Summer of 2008, John Resig ported the 2D context of Processing to Javascript for use in web pages. Much like the native language, Processing.js is a community driven project, and continues to grow as browser technology advances.

Short version: Microsoft (who now owns Danger, the makers of the Sidekick) decided to migrate data from one storage network to another. That migration failed, and corrupted the data. Okay, annoying, so restore from the backup, right?

Wrong. No backups. None. Zero. El zilcho.

So millions of Sidekick users awake this past weekend to find that all of their data are gone — or, in the best scenario, the only data they have are the most recent stuff on the Sidekick itself, and if they let the device power down, they'll lose that, too.

You can't say I didn't warn you.
