Metamorphosite
Metamorphosite is a living site that houses a bunch of articles I've written and changes for every new visitor. The goal is to determine the optimal layout to increase time spent on site. The site adapts its layout based on an aggregate of unique user attributes continually moving toward an optimal design.
I wrote the entire site from scratch. Check out the independent variable results!
AJAX
Ajax—which stands for Asynchronous JavaScript and XML—is a group of interrelated web development techniques used on the client-side to create interactive web applications. With Ajax, web applications can retrieve data from the server asynchronously in the background without interfering with the display and behavior of the existing page.
