This has to count as yesterday's thing as well. It will probably count as tomorrow's as well because there is still more to be done with it.
That said, I am pretty happy with my TARDIS. I'm not particularly experienced at Cinema4D but with a little help from Lynda and Cineversity I muddled through.
I also discovered the entire TARDIS building community. I would especially credit the TARDIS Builders' Handbook.
