* I found a [color palatte](http://www.colourlovers.com/palette/1220087/Dreaming_in_Santiago) on colourlovers and I went with it.  I think it looks pretty decent, and I have a pretty bad eye for colors, etc.
* I added a new font from google fonts, Fira Sans.  I like using sans serif fonts that aren't too goofy for headlines, and a serif font for text that is inline.  A designer friends of mine gave feedback before about that on a separate project I worked on.  See that [here](https://gist.github.com/kenmazaika/c522bd963f0a60ed9c0a/raw/ff2f769557f03eaeb3588950eabdcdd2f0b183d4/theFirehoseProject_design_review.pdf)
* I made the laptop backgound ben added have a blue transparent effect to it, so I could put text on top of it.
* I added a couple of headlines on top of the laptop so people will get the gist of what we're doing
* I added a footer, right now it has pretty bogus stuff in it.

Before you look at the code I added, merge in Ben's changes first about view changes, where he removes the old guy, etc.
