Your favorite Lego custom!
 

I'm not talking about the sets, I'm talking about just taking random blocks and making something out of it, what's your favorite you've done?

My personal favorite when I was a kid, I mad an enormous (well to me it was) motor home. For a "kid creation" it was actually pretty intuitive from what I remember.

Another favorite that I've seen but didn't build myself was a pretty darn good G1 Optimus Prime made by Insane Galvatron of TFW2005. The thing even has and opening chest and everything. Just doesn't convert, unless you count taking it apart into pieces.

When I was younger I made most of the main Transformers. Most of them actually looked pretty good too, and they also converted with little need to take them apart.

My favorite creation? That would be my castle with a over the top tower with a skull at the top of it. It's home to my huge amassment of skeletons.
