The aim of this 'wikipedia' like is to propose tasks that eventually would be performed by someone able to do it.
The site administrators encourage the use of open source software to accomplish this. For instance, they propose Gimp for image editing of Maddie pictures and Blender for 3D models creation.
Not to forget, also, that the site infrastructure is provided by the well known MediaWiki framework.
Further developments regarding open source contribution in this field are expected soon.
