The following are sample slides, diagrams, presentations and an interface I have created. The are not created primarily for beauty, but function. I try to make them crisp. If they look good, that is always a bonus, so please don't judge them purely on aesthetic.
Sample Slides
The following are slides taken from presentations I have given to domain experts in 3D interaction. The material might not be understandable without the accompanying speech but the use of color, layout and animation show my design focus.
NOTE: These are Quicktime movies generated from Apple's Keynote program. Click on the movies to advance the slide. When the slide is finished, it returns to the original slide view.
 Chasm's Concept-Oriented Design
These slides discussing how a high level idea, switching a miniature representation of the virtual world on and off, can be broken down into very simple statements. Using these statements, we can create lower level constructs which drive the higher level functionality. The slides then discuss some of the advantages of this.

 A bit of animation
Using animation, I pulled together three different images to demonstrate my point.

 Breadth and Depth
Using animation again, I was able to show how concepts work to develop breadth and depth of an idea.

 Illustrating 3D User Strategies
Here I show how two different strategies were used by the participants to improve their pointing accuracy. In the first strategy, when the participants pointed near an object, the object changed color to green to help them in their pointing. For their task of pointing at the red target object, the participants were able to use the green feedback to point down the rows of objects and select the target object. In the second strategy, participants extended their arms out further so their hand jitter had less of an effect on their accuracy.

 Code Complexity Growth
This slide shows how code complexity grows with added functionality. This is only one in a series of slides I created to discuss this topic.

 Humor
This is a fun slide used at the end of my PhD proposal.

Sample Diagrams
The following are diagrams I have used in work for papers, presentations or the web. Click on any of them to see a larger view.
 Chasm Splash
This diagram has a lot going on and because of this, was only used for splash pages. It was broken down into simpler diagrams per topic as needed in my work.

 3D Interface Specification
This is from a presentation I did about specification and standardization of 3D interfaces.

 A Random Slide
A random slide from another presentation. I thought it looked nicely laid out.

Sample Presentations
The following are some presentations I have given. They are exported as pdfs from Apple's Keynote application. Because of this, the animations are not shown so some items may overlap and some images are not shown because they are movies and come across as white blocks. Despite this, I think you can get the idea of the look I was going for in each presentation.

Sample Interface
This is a screen capture of the GUI to my dissertation. It was never full optimized as it was intended for an expert audience (meaning I did not have to worry about walk-up-and-use utility) and the goal of the dissertation was not to produce a GUI. That being said, it was tested on domain experts, given a heuristic evaluation by usability experts, and modifications made after doing walkthroughs with the user population.
Chasm GUI Screen Capture
This shows the main user view of the system. There are lots of screens which update as the user clicks around. It was created in Java swing.
For more information, see the Chasm Wiki. It has more information about Chasm and screen shots but since it is a wiki, it is constantly changing.
