In celebration of Information Aesthetics' birthday, Moritz Stefaner of Well-formed Data adapted his elastic lists concept to all five years of infosthetics posts. Each white-bordered rectangle represents a post, and colors within rectangles indicate post categories.
Select categories on the right, and the list updates to show related categories. Similarly, filter posts by year, author, and/or number of categories. Select a rectangle to draw up the actual post.
Go on, give it a try for yourself. Excellent work.
And then head over to infosthetics and wish it a happy birthday.
