Community Project: Add your part to this scene

Sketchfab community member pinguinoconpulgares has launched an interesting community project: you can download his airship model as a .blend, add to his model and then upload your version. All entries can be browsed through a tag gallery: #multiverseproject.

I have decided to try to try to make an experiment in the sketchfab comunity, I uploaded this steampunk airship thing, and I dare you to download this model and add whatever you want to the scene, and then publish it on your account, then ask the people to add something to the version you uploaded and so on… lets see how it goes :D
I hope someone follows it
The rules are:
- Add the tag multiverseproject
- The models can be done with any software and uploaded in any format
- Download must be allowed so others can download it and add their part.
- Don’t touch the lightning of the original scene or at least keep it similar.
- Credit me and other artists who work on this.
- All the uploads must be textured with baked render of a white material.
- All the uploads must be shadeless.

Hey Bart, the first tag gallery link appears broken. It links to BlenderNation rather than SketchFab.
Fixed it, thanks!
