There is probably a lot more I can say about this brilliant project but I'm not sure it will enhance your experience. And since I'm short on time this week, I'll shut up and let you enjoy this sample video by John Herschend and Will Rogan. Be sure to check out the website for more fantastic interviews and prompts, as well as instructions on how and where to post your responses.
Oh, one last thing. My response to this assignment would be to create a real life Clippy (the paper clip that used to haunt Microsoft Word). My Clippy would solve all my computer conundruns with cute Minion like expressions and exclamations, then offer encouraging or sympathetic comments when appropriate. Unfortunately, I'd need a wand for this and I don't have one.
