Thinking about the plight of the academic member of staff who has trouble remembering students from photos. https://www.youtube.com/watch?v=dyVo4sD2LiU
Something like Thinglink might help.
Students could add information about their interests, background, aspirations via links to existing work or stuff they like.
I made a quick one from my cat's point of view to demonstrate.
I also like the idea of short video responses, like a Vine to introduce your self https://vine.co/
, which i might have a go at later if I get time.
