I recently got into Half-Life 2 (who hasn’t? Sheesh) and more specifically, Garry’s Mod. Pretty much, it’s a mod that allowed you to spawn and throw around, and then put together and blast around some more anything you want.
But that’s not the point. I got this idea from reading their forums, and decided: “Hell, why not for ET?” So let’s do this.
The idea of this is to make the most longest contraption you can that in the end, does nothing but the most mundane task. Think of a long domino effect of random objects doing random things to eachother to move it further along, just to lift a flag.
The author of these sort of contraptions has named it, for some reason, “Goldbergs”.
So lets see how long all of your mappers can waste your time for just a simple task. Good luck!

Well, maybe sometime if I get really really bored AND I am drinking a gallon of espresso.
