Pranav Mistry, an MIT PhD candidate came up with this brilliant idea: Integrate Digital with the Physical World. (keep your patience, the fun starts a little later in the film)
It started with using the computer mouse, and cost him $2. And now, it is a genius invention that will be something to look out for in the near future.
What’s the lesson?
Every idea starts with a simple idea. And all it needs is a little evolving.
Oh, and great ethics (open source) at a great event (TED) that has a great marketing platform (sharing) is definitely a good way to market your idea.
