3d pens are great for inspiring and developing technology for three reasons. Accessibility, tangibility and inspiration. Accessibility, in this context, means accessibility for a student to use. While the actual pen may not be that accessible to schools, any student who knows how to use a pen can use a 3d pen with minimal tech support. Further, it is actually more forgiving than a regular pen, with straight lines being much easier to create.

Tangibility, means the ability to have a thing to show people. There is nothing quite like having something you can show to people to make you feel proud, and that is valuable.

Inspiration is perhaps the least descriptive term but in this case it means that it encourages students to use them. Figuring out how to best use the pen is both fun and it is also comes with immediate feedback.

Ultimately this supports creativity in the sense of 'innovative solutions to problems'. The falling of the balls is intuitive and easy to experiment with, again with that rapid feedback for quick iteration of ideas.

With ramping difficulty it lets everyone find a level they can't overcome easily and has to apply their knowledge of the subject to overcome. In short, it is a game. A reasonably fun educational game, but ultimately there's nothing like a game for engaging kids and making them think a little outside the box.

Essentially anything that lets students create stuff could have gone here. However, iMovie is best because it does not require much prior knowledge. I know from personal experience that drawing is fine if you're good at it, but if you're not it's frustrating. However, we've all seen trailers and most people could have a reasonable crack at making one. So for accessibility reasons, I think this is the best 'creation tool' (3d pen aside) discussed.
