YouTube have introduced a text-only mode for April Fool’s Day – TEXTp. If you view a video, where the choice of quality – 360p, 480p, etc. – is, you can choose TEXTp. Here is what I look like in ASCII characters giving my cryptography talk (click to enlarge):

Here is a link to my video in text mode, for as long as this feature is available: “Substitution ciphers: Ancient, Renaissance in TEXTp“.

UPDATE 2: Following the removal of the feature, see the next post, “TEXTp lives!“, for a video of TEXTp in action.
