I haven't had a chance to work with LEGO for a while, but I finally got around to building my Darth Vader picture.
This is a similar technique I used when making the Volition logo.
These are clear LEGO plates and studs layered on top of each other to
make different shades of gray. Up close, it looks like a jumble of
bricks.
I tried to introduce some shades of blue with this build, but I found that I could not control the color as well as I could control the amount of gray. In the end, I couldn't stand looking at the blue and just went back to black and white.
Based on the photograph by Stefano Buttafoco.
Hopefully soon I can get back to some of my other LEGO projects and get some new write ups with plans.
