Here's the summary:
Fri, 24 Jul – 14:30 PM | Jennifer Claudio, Typographical expression of emotions in a variety of alphabet systems
Contemporary writing often uses stylistic elements to emphasize words, and in a world of social medias and text messaging, it has potentially become easier to change the shapes or capitalization of a letter rather than using an alternative word with strength of connotation. This convenience lends itself to the nature of the Latin alphabet (or other alphabets with distinct capitalization), but is not a method that occurs in alphabet systems without capital letters. This presentation explores the use of a variety of type attributes including color, typeface, and size which are used to convey emotional charge in a selection of languages including English, Cyrillic, Korean, Arabic, Bangla, as well as the typographic advantages and drawbacks therein.

I think it's going to be great, and a few other cool MR people are already on board. I'll try to make it live, but if not, I'll be watching all the talks and writing summaries at a future date (for my blog).
