As I was shopping for the real bricks on Bricklink to make this LDD design a reality, I noted that many of the elements used didn't exist in the LEGO parts catalog until just a few years ago.
It's inspired by the Dorvack Powered Armor designs from the early 1980s. I used LDD to design the model, then Bluerender to render the wire frame views. I used Photoscape to put the views together into this animated turn-around.
