Celebrating our students' passion and creativity

Hi everyone. I'm thinking about designing an event or perhaps a competition for my Australian school's students to share how their iPad helps them to explore and follow their passions. I think our emphasis would be on sharing what's possible and celebrating our students, rather than a fiercely competitive event. The possibilities seem endless! I'd love to hear from anyone who has done something similar or who might like to design and implement an event like this together. Thoughts?
