A classic 1868 technical reference, "507 Mechanical Movements," is now available online with animated illustrations. The original book by Henry T. Brown showcases mechanisms and devices.

While not all animations are complete yet, many are ready to view, identified by color thumbnails. Users can browse through pages using the prev and next links. The site is gradually adding more animated movements until all 507 are finished.

Visitors can subscribe via Facebook or Twitter for updates. The project combines historical illustrations with modern animation to make these mechanical concepts accessible. For more details, check the About page.
