I’d like to announce the first public release of PNGPong, a cross-browser solution for displaying transparent PNGs on the web for IE, Firefox, and Safari using Flash, Javascript, and DHTML.
Create 1 PNG, use 1 Javascript call, and no Filters or tricky CSS.
For more details visit the PNGPong project page on OSFlash or check out the PNGPong project home for a full description and downloads.
