A friend of ours had to rent a port-o-john while some work was being done at their house. We snuck over at night and transformed it into a TARDIS or rather TerDIS. Looked quite good. I really DO need to get some photos. Sadly, it's a lot smaller on the inside than it is on the outside.
I still haven't made up my mind if I'm going to get one, though. I only got my Soul a couple of months ago, and I'm still making up my mind about what I want to do with it, as far as appearance goes. Lemme know what you think when you get it!
I have a secret to tell (well not so much a secret). I've been making a cedar rail fence around the garden and sawed out a chunk of the red heart wood on the table saw, and made a little birdhouse for my soul. It's slightly noticeable as an air freshener.
