This video was captured in Guatemala, back in 2007, where I was staying with friends for a youth camp at a small resort.The ants circle took place outside the eatery, after breakfast. The phenomenon only lasted a few minutes; when I returned about an hour later, most of the ants had already found their way into the nearby plants.

This is the video of a free animation assignment for the course "Introduction to 3D Computer Graphics" at York University. I wrote a program to display an animated scene that included a combination of hierarchical objects that move about, as well as texture-mapping and camera motion.
