Collateral is my favorite kind of damage!

Legopard, the challenger in the current Iron Builder contest, has built this excellent siege tank from StarCraft 2. Not only does it look great, it also transforms! 

Knowing that this was built for Iron Builder tells me it couldn't have been built in more than a few days at most, probably even a single day - and that blows my mind. It's a rare builder who can create something this good in such a short timeframe. Nice one, Legopard, and best of luck in the arena. 

(The seed part is the silver Technic connector, used 18 times; Legopard's challenger is Tim Schwalfenberg (One More Brick). Keep up with the current IB round here.)
