Design improvements

The current design is, well... plain.

I'd be interested in trying to step up my designer-game and create a higher-conversion landing page with greater chance of attracting users. It would be nice if we actually wanted to point people toward the website instead of the GitHub (definitely not the case currently).

I found a couple interesting/relevant links & articles:
- [A WYSIWYG landing site generator for startups](https://designmodo.com/generator/) - Could be a good way to explore the design-space.
- [Article on how to create a high-conversion landing page](https://unbounce.com/landing-pages/writing-high-converting-copy/)

We should probably include a big fat link/button to the GitHub that is seen by users immediately upon arrival; programmers/hackers are likely to find that more interesting than a landing page.
