We never had the patience for stuff like this. LEGO is amazing, and a huge part of practically everone's childhood, but this is some OCD type of dedication.

LEGO builder Rags naRock has his created this Metal Gear Rex, and has shared the instructions for you to do the same. Putting $900 worth of LEGO parts into creating this massive mech is some med-school level commitment. Also, the thing has moving parts.
