Google's Logo Today (31 Mar 2011)

Hi,

Have you seen the Google logo today... they are celebrating Robert Bunsen's 200th birthday...

How did they create that graphic... it looks like flash but it is clearly not... from the source code i can see that it is a png but how do they have motion in the image, thanks in advance...

Motion is working in FF but not IE

Any ideas how they created this, thanks in advance

@ hanccocka - so does this tool basically take all of your PNGs and make a clip out of them, then save the final version as a PNG itself...

Why does the google image  show up the way it does, different versions are within the same image

Yes, These applications will create an Animated PNG from a set of static PNGs. Each frame you give it must have the same metadata (size, colour depth, transparency, pallete, etc.)

Different frames in the Google Image.
