LEGO Pacific Rim — Cherno Alpha
Now while I wasn't actually that impressed by Pacific Rim the Jaegers themselves were pretty cool. And they're just begging for LEGO models.
Like this one of Cherno Alpha by Jason Corlett.
Apparently his micro scale build stands almost 3 feet tall, contains around 5,000 bricks and took about 70 hours to build.
Hours well spent I'd say.
