This is a terrific open source tool for Web designers: Browsershots (Inactive as of 2011)
Browsershots makes screenshots of your web design in different browsers. It is a free open-source online service created by Johann C. Rocholl. When you submit your web address, it will be added to the job queue. A number of distributed computers will open your website in their browser.
They make screenshots of your site in all the browsers you select for Linux, Windows, Mac OS, Gecko, and KHTML/WebKit and upload them to their central server.
Started in late 2001, GOK was created at the ATRC (University of Toronto) with funding from Sun Microsystems. GOK (an award winning software that provides text entry and graphical user interface interaction using only switches and/or mouse devices), is an on-screen keyboard that provides access to the GNOME desktop through dynamically generated keyboards, and text entry by one of the provided alphanumeric keyboards, or a dynamic keyboard based on the users current system keyboard driver, or even a user-made keyboard.
GOK keyboards are created in two ways. Dynamic keyboards are created (while GOK is running) to provide access to the desktop and application GUIs. Premade keyboards are specified using fairly simple xml (".kbd") files. GOK allows the creation of new ways of operating the GOK keyboards by XML "access method" files (".xam") files. These files also provide the description of the user interface for the access method's settings.
