LEGO + Tools = Win
While I'm a purist when it comes to building, for animation I break all the "rules" all the time. We glue parts, drill them, cut them and modify them to make them work for the project, it's just practical to get the job done. I know it would make a lot of you cry to witness all that activity with tools and bricks in the same space, but here's a fascinating animation by BricksBrosProductions that has both, and as far as I can see, no bricks were harmed in the making, enjoy!
