I have been working on the gif and steg all the day, LSB does not seem to have any menaingfull information, at least not ciphered.
I have also tried a lot of programs and algorithms but always empty, the only one that is a bit promising is GiffShuffle (http://www.darkside.com.au/gifshuffle/) it always return some information but that doesn't need to imply that there is information in there, I have tried with a lot of passwords but haven't found anything.

If someone has a unix machine it would be great to try stegdetect 0.6 ( http://www.outguess.org/download.php ) as it is not compiled for windows.

I am puzzled about the url at the end of the Gif and the gliders, I am thinking that the next step is a custom GoL that is placed in http://whit3r4bbi7.com/ but we need more hints or crazy ideas.

Edit:
Damm, after coin artist message, maybe we are looking were we shouldn't, we still have the 0,3 address and the first message to decode and maybe we have now all the information to solve those.
