If you go to this link: Ant Simulation in Second Life, you will be able to see a video of "a simulation of how ants find food, leave a pheromone trail for recruiting and occasionally run into dead ends". According to the poster, Brady Forrest of O’Reilly Radar, the video shows what you can do with Second Life’s "scripting language and avatar creation tools".
Now I have not watched the video, but I’ve seen plenty of such simulations and animations in regular boring old life. So I wonder why the Second Life aspect is a killer app (or even a killer ant, groan) here? Don’t get me wrong, I am not a Second Life detractor by any means, I am aware of its great educational and innovative potential as well as it being a place popular with gamers for all kinds of frivolous pursuits. But I am genuinely puzzled as to why this video is better in a virtual world than in our world. Whatever, it is probably a fun video to watch if you like watching videos of ants.
