The scroll in this animation was modeled after photographs of scrolls from ancient Jewish synagogues. The scroll may resemble the scroll the apostle John saw in the book of Revelation. Seals were placed on the inside. As the scroll unrolls sections of the internal seals are broken.
Then I saw in the right hand of him who sat on the throne a scroll with writing on both sides and sealed with seven seals. (Revelation 5:1 NIV)
The scroll animation was prepared with 3ds Max and Photoshop. See the 3D interactive Scroll.
