I'm not a Graphical or Artwork specialist, but i suggest here, for the future versions of Sabayon, the creation of a #D wallpaper for default.
For example, may be a "room", in witch the Sabayon Logo may be "into" this room and converted to an 3D logo (may be using Blender?)
For the room, similar, nor necessarily for Sabayon, but see this for example.
