3D boards are always fun to look at and watch develop (never played on one before). What stops me from even attempting to create my own (other than the space, time and treasure involved) is the difficulty in customization. Making everything modular so you can place the doors and things where you need to is a must, but it greatly adds to board setup time, space requirements, etc.
And while having a physical board is always superior, building it digitally would seem like the most versatile solution (and those pictures in the opening thread look mighty cool!). Then again you could build it out of legos (and probably end up spending a lot more). I love the creative solutions and inventiveness, it's great to see, and maybe someday someone will convince me that it's worth my while to try it too.

Different types of painted foam see like a great solution, much cheaper than wood or plastic, and still look decent, but I'm only judging by what I've seen others doing.
Carry on with these awesome projects, I want to see you succeed!
