@Lapp from Pinebox normally helps people out with this kind of thing but I think he might still be on holiday.
The artist responsible for many of the homes has good images on his website, but I'll confess I'm not sure about the legal rights regarding using images etc. Outside my skill set.

Hope this helps and sorry if misunderstood the request. Good luck promoting your event.
Edit: the artist used to sell playmats, but the page is down. I found an old screenshot in case you want to try the supplied email address. http://i.imgur.com/zL4dlTq.jpg
