Ask HN: Examples of great concept pitches? Advice?

[ysh4u]

I'm making a pitch for a concept competition in two days. Working on the presentation now. Are there any good examples of concept pitches that I can learn from?

Background: it's a college competition with $40,000 at the end. We're very excited to be in the semi-final round and at the stage where we actually get to present (in person) our idea.

Good stuff. Thanks!

Best way to pitch a concept is to build a prototype. Design it in Photoshop.

While I certainly understand the merits of having a prototype, the competition is structured to focus on concepts (we don't have a lot of time to prepare).

If we were to build a prototype we would want it to be really awesome, which isn't too realistic right now.
