The other thing that bothers me is how items have a more traditional rectangular representation, but also a more abstract physical-form-based representation. These aren't necessarily next to each other or even near each other. Its confusing when I highlight something and something else somewhere else on the page lights up. It's also frustrating if you click on one thing, then go back and click on something farther down and its the same thing.
Like this a lot!
Agreed with j.edmund on the double images. It's not so much an issue when there's a clear link between them and they're close together. But it's not always the case. The two Lime-images are too far apart, and the Other Cool Things are seemingly not part of a greater ensemble (which they aren't).
On the centering, it looks fine on my screen because my browser is rarely full screen (I keep it at around 1400px). But I see how it could look weird for others.
But all in all I really love this. Like the colorful hovers on the text, like the hover-animation on the projects and that tidbit with the chair is a very nice personal touch.
