I know I'm joining in late and only have a few weeks experience with 3D but I'm going to do this. And, I will have a finished model to submit in time.

I think I'm going to do some kind of a robot since that was what I was considering to do for my next project anyway. I will probably get my design ideas from steam engine trains and such. I'll work on a sketch tonight and post whatever I have, tomorrow. My goal will be to not get too detailed since I'm so short on time, but detailed enough that it won't look too lame.
