An image showing the Flash animation logo SWF Flash logo is a link to a Flash animation.

Flash animations are embedded into the pages of all my D&T Modules but there are pictorial links to the animations on this web site so that devices that cannot play Flash animations will at least show a jpeg screenshot of the animation.

If your PC or personal digital assistant (PDA) can play Flash animations you may click on an image showing the Flash animation logo SWF Flash logo to view the animation in a new window.
