Visitors to this year's Trojan Horse was a Unicorn digital arts festival in Troia Portugal were wowed by Aoi Yamaguchi's opening performance, in which the artist created beautiful large-scale calligraphic figures in response to pieces of music.

Chris caught up with Aoi and discovered more about the ancient art of calligraphy, including its range of 2,000-plus characters, the importance of the tools she uses to create them, and its role in the digital world. This isn't just about writing, though — Aoi talks about overcoming her fears, following her dreams, mastering an art form, and expressing herself. There are lessons for everyone here.
