Had a relative pass away recently so I didn't get the time to do the topic for today. I'll try to do it on my flight back to CA tomorrow. I know... No excuses!
In the mean time, Matt and I talked about it and we decided to have some historical reference for this one. To try and do things that would require a bit more research, and the application of that research into the paintings.
Here's a link to get you guys started: http://en.wikipedia.org/wiki/Valhalla
P.S. Feel free to suggest any ideas you may have, as I had a hard time coming up with this one today! I guess the way we can do this is that we just leave comments on that day's post and suggest topics in there for the next day.
