I wonder how this is done. This gif from Micael Reynaud is amazing. Made using 15 portraits. Via fastcodesign.
Gian fish sculpture constructed from discarded plastic bottles at Botafogo beach in Rio de Janeiro, Brazil, on June 19, 2012. At the moment there is the UN Conference for Sustainability there.
Germany just won against Denmark. Next opponent Greece. I just did my first gif and uploaded it to tinypic. I did this gif with picasion.com and the pixel art with pixen. It is really easy but I did not like the blury edges.
I just stumpled over the pixel art generator pixen. It has everything you need to do great pixel art. You can create pixel art really easy, you got layers and you can also do animations. This is a great free alternative to photoshop. Unfortunately this is for MAC only. You can download it on the App Store. You can find the tutorial on github.
