Neo4j is a graph database, a fully transactional database that stores data structured as graphs. A graph is a flexible data structure that allows for a more agile and rapid style of development. You can think of Neo4j as a high-performance graph engine with all the features of a mature and robust database. The programmer works with an object-oriented, flexible network structure rather than with strict and static tables, yet enjoys all the benefits of a fully transactional, enterprise-strength database. The community edition is GPLv3 licensed, while the advanced and enterprise editions are AGPLv3 licensed.
ModuLiq is a lightweight Web content management system. Web pages can be made up of various pieces, such as a header, footer, menu, etc. When changing a module, such as your header or footer, all your pages that use that module will be updated at the same time. A liquid layout means that Web pages flow to fill the user's browser window, no matter what the size or resolution is.
Pagekite is software to make servers on "localhost" visible to the wider Internet. It can be used by Web developers to show off their works in progress to clients or colleagues, embedded developers who need direct access to devices in the field, or as an alternative to dynamic DNS for individuals/hobbyists who would rather host their own content than rely on 3rd party hosting. It creates and maintains a tunnel between your server on localhost and a remote "front-end" (a reverse proxy). Only the front-end has to have a visible IP address; the server itself can reside on a heavily firewalled computer, a mobile device, or even an anonymous node on the Tor network.

Design Center is a Web application that allows users to change the colour of different layers in a photo. In a photo of a bedroom, there could be layers for the walls, the ceiling, and for the floor. The application lets users change the colour of each and see how a new paint job would look. If used on a furniture store's Web site, different layers could be used for beds, chairs, lampshades, etc. to allow customisation by users.
