The Intersection Aggregate is a fun visualization defining the relationships between objects with Casey Reas, William Ngan, and Robert Hodgin. Commissioned for display at the Whitney Museum of American Art, the version on this page is a slight modification of the original algorithm (it simply uses color).
Casey suggests we write programs to visualize the same simple instructions:
A surface filled with 100 medium to small sized circles. Each circle has a different size and direction, but moves at the same slow rate. Display:
A. The instantaneous intersections of the circles.
B. The aggregate intersections of the circles.

We were not allowed to see each other's programs until the end. In this way we found many surprises of similarities and dissimilarities between our implementations.
Circles move only horizontally. I
intentionally kept the movement of the circles simple because the drawing technique was already so complex that the underlying structure was lost.
