 From 2011, that was Rubik's cuber David Calvo speaking with former As It Happens host Carol Off from Bilbao, Spain. You've been listening to As It Happens from CBC, heard across the United States on public radio. You can also find As It Happens anytime by downloading the CBC Listen app. I'm Chris Howden. Thanks for listening. And I'm Yigit Koksal. Take care.
