    This was the first video I ever watched on YouTube. Rewatching it now makes me feel very nostalgic.

    Lego: exist People: reality can be whatever I want it to be.
  • hey, i discovered this video when i was like 8 or smthn and i truely believe you have single-handedly raised me to be the person i am today. i cannot thank you enough.
  • It took me more than 10 years of surfing, but the moment has finally arrived: I have found the perfect video. I was hypnotized. And when it ended, I felt cleansed. If I could give you a thousand thumbs up, I would. This is complete and utter perfection.

    I've never been this happy about blue balls in my entire life.

    If you make this huge and make a ball-shaped capsule that can carry humans and put it in the amusement park, everyone from all over the world must come.

  • @geluix69
    As a person who works with PLCs and robotics this is a work of art in motion. Fantastic.

    I remember watching this as a kid every time i get bored, oh the good old days.
  • @mattlevens6382
    That large robotic arm near the end was crazy impressive
  • @captpicard6894
    Stunning, awesome, incredible and a whole load more of awesomeness. It’s insulting to call Lego just a toy when you see something as magical as this.
  • This is how my brain works. It does a lot of things, but does not really accomplish anything.
  • @tylersmith5449
    Thinking back, I can't believe how accomplished I felt when I built a nice little lego house...

    The ball factory by Akiyuki in the beginning of the video remains my favourite GBC. SO cool.
