A few days ago I was noodling around with my 3D sketch for this build, but I decided to use LDD to flesh it out a bit more.
It’s now so far from the original model in Tom Alphin’s book that I feel justified in calling it a MOC.
I have expanded the 3D sketch even further, giving the build two side wings surrounding a central raised core. The upper levels are on the diagonal again, to give a bit of dynamism.
I would like to build this one sometime, I need to gather enough trans light blue bricks first, however.
