You can follow the development in the facebook page or and in the portuguese blender forum and you can help by modelling some of the missing characters and props.
This is my small contribution for the project so far, I've modeled this character, "Robot da construção civil" from his reference drawings.
It still needs some touches and the rigging but it's almost done. The final renderings will be in black and white with a technique developed by Paulo Martins.
