Eco-Memory is the classic memory game where the goal is to find matching pairs of cards. The cards represent habitats, organisms, and cultural entities of ecosystems like the Boreal Forest, Coral Reef, Deciduous Forest, Desert, Ice, Intertidal Zone, Rainforest, Surface Zone, Tundra, and Wetland. The game includes a small synopsis of the organisms, the cultural entities, and the habitats themselves. The synopsis is available through an "About" button that you may click after finding a matching pair of cards.

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.
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.
