[0:01-0:21]: Robotic text-to-speech voice: "Very good. You have done well. You heard the word of omega and visited the library. The page of pound lead you here. Use the word 1260 to find the next step. We want those who are able to read the pictograms, not followers. Good luck. Goodbye."

Info and notes

 * The three links in the subtitles lead to three copies of the same file, sigma-private.asc. Using this key it's possible to decrypt PGP messages sent out by O, including those in IANVS and Hear the word of £.
 * In the description it reads "Hic est finis GANIcs", which in latin means "This is the end GANIcs". Combined with the message in E8 lattice, "Hoc est initium qUbHQ", "This is the beginning qUbHQ", the word qUbHQGANIcs is formed. When typed into a Youtube link (watch?v=qUbHQGANIcs), this leads to the video Post Sequentia.
 * The usage of the word 1260 (pronounced twelve-sixty) is currently unknown.
