Been tuck away in the garage building once again this time on a slightly larger scale for all my sins lol, this time this box is to be used for shows with its first outing being next weekend at Brighton 2012, this box can be used as 2m x 2m or 3m x 2m and is 350mm deep, and has a maximum capacity of 2 tons of dirt. Here are some pictures of the build.
Here it is in its 2m x 2m
