If you don't want to go to the trouble of downloading flash software and learning flash tutorials, you are free to download any of the large flash intros here for your website, blog, powerpoint presentation, etc. The thumbnails below show the background of each animation. Beside the thumbnail is the text that is animated, and the size (in pixels) of the animation. Just select the link beside each background image to see the animation in its actual size on a new page. To download the file simply click where indicated. After the download, click on the file and it will automatically extract to a folder named "3dsourceflash" (this makes it easier for you to find the animations later when you start to build a website) with an ".swf" (shockwave flash) extension.
