This is some impressive work from Lego maestro Baron Von Brunk, who previously made a five-foot working NES controller from our favorite plastic bricks. This time, he has built a completely transformable (no rebuilding required) Nintendo 64 console and controller. "No glue, paint, cutting, nor 3rd party custom pieces."
Even the cartridges transform into mini-sidekicks!
For more pictures and details, check out the Baron's Instructables page. It has animated gifs of the transforming process, even.
This is one robo-builder who can keep all Pretenders at Bay.
