The following three images were done as a part of hackathon sponsored by Lincoln Labs in San Francisco.  It was a "liberty-minded" hackathon that focused on using modern entrepreneurial thinking to find solutions to current economic and political problems.
Below is the idea I pitched, Informed Republic.  Think of it as a profile for political information.  The basic premise: As detailed by Public Choice Theory, people aren't fully politically informed because the "barrier" to becoming so is incredibly high - it's a full time job.  In turn, the repayment for such an effort is relatively low: unless you work in politics, the most you get is the satisfaction of feeling informed. 
The goal was to create a site where even a complete beginner could login, fill out a questionnaire, and have all relevant political information delivered right to him or her.  The content wouldn't be limited to news articles, but would also provide detailed profiles of politicians whose voting records most closely reflect the user's beliefs; events such as rallies and upcoming congressional votes; and widgets that help the user fully visualize how current policy affects his or her day-to-day life.

Issues are your "accounts"; they're the different subjects in the political dialogue relevant to your personal interests.  These are ordered according to which issue is "hot" at the moment.  Each issue is colored-coded; this color coding remains consistent throughout every section of the page.  For example, "Personal Privacy" is pale yellow.  This allows you to see at a glance the several other items relevant to Personal Privacy today: a call to action, a progress update, an upcoming event, and two "players" to learn about.
Issue Tracker is like a stock ticker for your issues: it tracks any progress, updates or changes to the matters you care about.  Content here can range from news articles, to live video coverage, to alerts on upcoming congressional votes.
Take Action offers suggestions for you to get involved.  It lets you know about upcoming rallies or fundraisers, alerts when to contact your Congressman, or can even present you with survey questions (sponsored content in this section could also be a potential monetization channel).
Players are all the people involved with each of the stories you care about, presented at a glance.  Clicking on an image would bring you to a "profile page," providing more in depth information about that person.  For example, a politician's profile page might track something like their political rhetoric vs. their voting record.
ALICE is a construction management company that uses machine learning and artificial intelligence to find the most efficient methods for scheduling construction projects.  The client wanted to take an industry not typically associated with academia or technology - construction - and make it something "elegant," "sophisticated," "academic," and "sexy."
Side note: after presenting their product at Stanford's annual BASES product showcase, the ALICE team took 1st prize in the competition and was awarded $20,000.
Branding and marketing material.
The symbol over the eye was inspired by a graphical representation of something called the Levi-Civita Symbol, which is used to calculate mathematical permutations - much the way the ALICE software calculates numerous permutations of the same construction schedule.
The graphic at the bottom is a city skyline in the form of a sine wave.
Branding and logo design.
Below is a mockup for a company called Makeably.  Makeably connects independent makers and buyers of low-volume, customizable products.  When I first spoke to them, they were facing some "barrier to communication" issues.  Buyers and sellers were having lengthy back and forth discussions before a product finally got made.  Naturally, a few of them lost interest, and the development of the product never moved forward.
When doing these mock-ups, I was presented with an interesting problem: find a solution that would simplify communication between buyers and sellers, and design a page that didn't "feel" like an eCommerce page.
You can see the original Makeably page here.
My first task was to create a unified color palette.  Every color in this mock-up was selected from above.
