The results of the Seasteading design contest are in and voting is now open. May 13 and the winners will be announced May 15.
Johan Steenkamp reports:
The seasteading design contest is finished. One can now vote for one's favorite
entry. Disclaimer: I made one with Blender called 'Akamai'- Johan Steenkamp.
On top of that, you can download the models in a whopping 690 Mb file. They're in all kinds of formats, but there's quite a lot of Blender material there as well. All files are released under the Creative Commons Attribution license. In order to prevent an immediate meltdown of their webserver I won't link to it directly. If you want it, you'll have to search for it! :)
Update: I checked the model download and the following models were present as .blend files: 4,6,13,17,18,19,21,22,24,27,31,32,33,36,39,40. Almost half of the entries were done in Blender!
