507 Mechanical Movements: An Animated Digital Index

"Bringing the timeless ingenuity of mechanical engineering to the modern web."

We are thrilled to present the digital version of the 507 Mechanical Movements index, which is now being static animated for the internet!

Current Project Status

While we are working diligently, we must admit that not every single animation is functional just yet. However, a significant number are already live for you to explore.

Progress Tracking:

• Total Movements: $\sum_{n=1}^{507} n$
• Status: In Progress

How to Navigate

To explore the gallery of thumbnail pages, please utilize the navigation controls located in the upper right-hand corner:

• Click prev to go back.
• Click next to move forward.

Our Roadmap

We are committed to completing the entire collection. Our goal is to ensure that every one of the 507 mechanisms is fully animated.

• Archive Henry T. Brown's original drawings
• Complete all remaining animations
• Finalize the interactive index

Technical Note: The underlying logic for the gallery navigation follows a simple sequence:

function navigate(direction) {
  if (direction === 'next') {
    currentPage++;
  } else {
    currentPage--;
  }
  updateThumbnails();
}

We hope you find great value and enjoyment in these animations and the classic technical reference work of Henry T. Brown.
