Co-Ment is a Web service for annotating, discussing, and writing texts online. The editing environment is wiki-like, supporting many syntaxes (Markdown, RST, and HTML), and allows for finely controlled layouts including tables and images. Users can comment on extracts of the text, and advanced comment navigation features allow new annotations to be discovered or the history of a debate to be browsed. It is also possible to set up an email alert for text edits or new comments. Import/export is supported for many formats including TXT, DOC, ODT, and HTML.
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.
