There works are derived from the works posted on TeX.SE:
http://tex.stackexchange.com/questions/39485/how-can-we-display-fireworks
The original works simply generate a multi-page PDF document and then convert it to an animated GIF image (by use of ImageMagick). I modified them so that animation will be embedded in PDF, by the aid of 'animate' pacakge.
The resulted PDF files can be obtained from:
-- firework-cmhughes.pdf: https://docs.google.com/open?id=0B4TklbcTMngmaFZwU0x6NmZ6NDA
-- firework-kumar.pdf: https://docs.google.com/open?id=0B4TklbcTMngmVS1sMmw4UE5tV0k
Note that animation will probably work only when viewed with Adobe product.
