"Ephestos" is a visual programming environmet for python similar to an IDE but with some fundamental diffirences. Ephestos uses its own GUI called "Morpheas" a very modular gui that not only is capable of offering a graphical user interface to the user, that interface is easily customisable by the user , made solely from small blocks called "morphs", with no required coding. Also the code is edited visually using morphs again to further help the user. For now the project is still in its infancy with many feature to implement , but is however a usable Blender addon that is constantly developed. Using any of the above button you can download the source or visit the repository at github.

Ace is a standalone code editor written in JavaScript. Our goal is to create a web based code editor that matches and extends the features, usability and performance of existing native editors such as TextMate, Vim or Eclipse. It can be easily embedded in any web page and JavaScript application. Ace is developed as the primary editor for Cloud9 IDE and the successor of the Mozilla Skywriter (Bespin) Project.

The Mozilla Skywriter project (formerly Bespin) is a Mozilla Labs experiment to explore ideas around “coding in the cloud”. We’re happy to announce that the project has found a new, permanent home as part of the Ajax.org Cloud9 Editor (Ace) and Cloud9 IDE projects. Read on to hear more about the transition and what we’ve learned along the way.

MIT Media Lab staff (the Open Ended Group) is working on a new kind of programming tool called Field. It connects everything. Not only various programming modules and components, but also different styles of generating, editing and testing code are provided. For example textual coding with auto-complete, visual coding, timelines, live-coding, flow-management etc.

— a development environment for making digital art
Field is an open-source software project initiated by OpenEnded Group, for the creation of their digital artworks. It is an environment for writing code to rapidly and experimentally assemble and explore algorithmic systems. It is visual, it is hybrid, it is code-based. We think that it has something to offer a diverse range of programmers and artists.

Based on ideas started at the MIT Media Lab, Field was in development in-house for around 6 years. But for the last 16 months it has been quietly available online as an open source project. We are pleased to announce the initial "beta" binary open-source releases for Intel-based Macs OS X 10.5 or 10.6.
