Suffice it to say I have no concrete ideas, but I have trains of thought that I think may help us create something more meaningful to a larger group of people...
From a story standpoint...
If anyone has seen 'The Blue Umbrella,' a good portion of that short film is based on the concept that humans see faces in inanimate objects. Cars, gutters, windows, etc. I believe founding our story in a concept that most anyone could relate to might be a good way to get a basis for a story. The key, is to provide some kind of twist. I personally like the idea of basing a story off of the idea of not being able to find something you just put down, or walking into a room and forgetting why you're there. The twist could be where this takes place, or who is doing it.
From a lighting/texturing standpoint...
I really want to do something that provides me some artistic leverage. Not to make something my own, per se, but to simulate something other than daylight. I want to be able to expand my portfolio of lighting capabilities. Thus far, in this class, i have focused mostly on simulating normal daylight, and while that's okay, I think branching out would be fun. And texture wise, my ultimate goal is to push them the furthest I ever have. This doesn't necessarily demand a wacky and wild concept, but maybe just something with a bit more nuance than a house.
These are just building blocks with which to play with (or even discard).
