We may be guaranteed never to see official Ghost in the Shell LEGO models, but that doesn’t stop LEGO fans from building their own Tachikoma, Fuchikoma, and other “Think Tanks” during what is now the annual Marchikoma challenge.

Chris (Ironsniper) puts the new olive-green LEGO elements to good use with his own entry, full of great shaping despite the limited parts palate.

The light and dark grays Chris uses for the non-olive portions are a great example of using different shades of gray to mimic different types of real-world metals — a subtle type of color-blocking missing from less-sophisticated builds.
