Sirix is a versioned tree-based storage system. It provides Snapshot Isolation through MVCC and is best suited for flash-based storage. The tree encoding is suited for heavy update operations. It provides diffing algorithms either to import diffs between currently shredded (imported) XML documents to update a tree structure or to get the differences between versions of a tree structure. A GUI provides several visualizations for comparing imported tree structures.
Page Transitions shows transitions when a user leaves a Web page. It can produce an animation effect, so when the user leaves the current page to another, the effect is applied to make the page disappear and the new page appear. The object can compose an animation defined programatically or execute one of many types of pre-defined page transition effects like fading, panning, shrinking, rotating, skewing, etc.
xLayers animates page elements stacked in different layers. It traverses the list of page elements of a given container element and changes their positioning properties so they appear stacked as layers on top of each other. Some elements may be explicitly excluded from becoming layers. The position and size of each layer can be adjusted by the user with the mouse or animated automatically at a given timing rate.
SpotlightJS shows a spotlight over a Web page. It can create a transparent canvas on the top of the Web page with a dark area and a light rounded spot area which make the content below it appear as if it highlighted by a spotlight. The spotlight can be animated so it can move at a given speed. Callback functions may be invoked when the user drags the mouse over or clicks in the spotlight or the canvas area, as well when the animation starts and ends.
Whiteboard lets the user draw freehand graphics on a Web page. It can create a canvas object for the whiteboard (if one does not exist) and let the user draw on the canvas area by dragging the mouse around. The color, thickness, line join, and line cap of the drawing pen can be configured. The object can also clear the whiteboard, export the coordinates of the drawn lines, or import previously drawn lines.
Gravity animates HTML page elements using the laws of physics. It uses the Box2DWeb library to animate given page elements so they move, rotate, and collide. The gravity acceleration and direction are configurable. Given callback functions may be invoked when objects collide. Objects' speed and rotation may be affected when the user drags them using the mouse pointer. Each page element can be made static or animated. Animated page elements may include the respective children elements. The elements' friction and density properties can also be configured.
