Optimus Prime

For the build I lent a Battleblades Transformers toy from my friend Barry Bosman, who is a massive Transformers fan. This helped tremendously.

 

Its transformation is doable in LEGO, but it is horrendously complicated and awkward and some bits will inevitably fall off in the process. I'll likely revisit this at some point to add a more Technic structure to it.
