Mesmerizing LEGO Machine.

[tridim]

Crazy humans and their "toys".

1. Someone has way too much time on their hands. /nt

[Archae]

2. Too much time playing with their balls.

[Kablooie]

3. Someone is very clever, very rich, has plenty of free time and still has a sad life.

6. As I understand it, each module is built by a different team.

The modules only come together at the very end.

4. How delightful that the first three responses do nothing but mock the person who built this

Bravo, Lounge, Bravo.

[surrealAmerican]

5. That was fun.

I'm not sure why it bothers me that, the only time the balls were sorted, they got recombined in the next step. I wanted them to follow different paths.

7. I love that stuff.

Cut my teeth (and a finger or two) on Erector Sets when I was a kid.

These Lego robotic systems are a great way for kids to develop an interest in engineering and mechanics.
