Love it:
This is a working particle accelerator built using LEGO bricks. I call it the LBC (Large Brick Collider). It can accelerate a LEGO soccer ball to just over 12.5 kilometers per hour.
I’m even more enamored of this one:
[A] kinetic sculpture of a human head. As the top of the head opens it reveals a wonderful world of pure imagination built using LEGO bricks.
good stuff!
