Design a logo/icon for my iPad application

Presentation Pad

I'm an iPhone/iPad developer working on a presentation application for the iPad called Presentation Pad. The goal is to launch on day one of the iPad application store.

Presentation Pad is intended to be used in situations where you need to give a one-on-one presentation or a presentation to a few people in an informal setting. Think of a salesman talking a client to lunch, and presenting new products between courses. Or a startup founder pitching an idea at a coffee shop. These are the sort of situations that Presentation Pad will excel in.

The Presentation Pad organizes pages in a grid, and allows the user to quickly navigate between adjoining pages in whatever order they choose. The goal is to be able to adapt the pages you're showing to the situation, changing the flow of the presentation it progresses.

Attached is a current screenshot.

This is based on an idea by Seth Godin, the well known internet marketer, presented in this blog post: http://sethgodin.typepad.com/seths_…g-pad.html

The target audience for this application are business people and salesmen/women who make lots of in-person presentations either one-on-one or to small groups. Think travelling salesmen, startup founders, business executives, artists making presentations to clients, etc.

This will compete with/complement applications like Powerpoint and Keynote.

I need a logo design and a matching springboard icon. I need both in a vector and raster format.

The logo should be on the scale of 500px on it's larger side (I'll leave it up to you to decide the aspect ratio).

The springboard icon (which is what shows up on the ipad home screen, similar to an iphone, and which the user uses to launch the application) must be 512px by 512px. It should not have any baked in gloss or rounded corners (those are added by the ipad automatically).

Some thoughts:

1. The logo and icon should convey that this application is fun to use. Something with bright colors would be great. However, it shouldn't feel childlike.

2. At the same time, it needs to be somewhat conservative, given the target audience. It should be something that a salesman in a conservative industry wouldn't be embarrassed to have seen by a prospective client.

Other than that, this is really open ended. Feel free to experiment!

Update:

It would be great to see designs that focus on the concept of ideas flowing/exploding/blossoming/floating out of an ipad/presentation. It would be great if your design can focus on the presentation itself, rather than the person giving the presentation.
