Ryan and Cassie Creighton at TEDx Toronto

The ultimate capper to the delightful tale of a father and daughter making a video game together was this TEDx Toronto talk, in which a now 6-year-old Cassandra recounts the tale of how she co-created the worldwide hit game Sissy’s Magical Ponycorn Adventure. Her father Ryan steps in for the back half of the talk, making a case for updating public school curriculum to include a new literacy – computer literacy – aimed at students as young as Cassie.

Spoiler alert: cardboard robots win the day.
