Creating Something to Better Us

For a class of mine I have to "present an idea I have for bettering us in some way". Now this sounds vague and it is, but I don't think that's a bad thing. It can be anything from making some ergonomic to solving a world crisis. I'm not sure what I'll do it on yet, I do have some interested I'd really like to explore more into though....

• Crowd Sourcing (and how to make it as internationally friendly as possible)
• ARGs (already did a big presentation and created a 10 minute mini ARG last semester)
• Active Cross Media Marketing (close to ARGs, but without the story
• Experience Design (how to design a space in reality or online that mold how people feel and react)
  

I really like the idea of getting people involved with a product or idea rather than being talked at. All of those bullet points can be intertwined, but luckily for me I think that means I'm narrowing down what I want to do after I graduate next spring.
