A video showing the layers of a high contrast TDI CT (time delay integration, computed micro-tomography) test scan of a bundle of 20 locked letters. Using historic letterlocking formats, iron gall ink, quill, and sealing wax , the #UnlockingHistory team made up the batch of new letters for testing, writing secret messages inside, folding them using historic letterlocking formats, and sealing them with wax. The Unlocking History team and their collaborators developed the technology to virtually reveal the contents and folding patterns without tearing open the letters.
