Northern Lights Circular Wander Demo

This was a fun quickie. I’ve always wanted to try creating Northern Lights with Actionscript, and here was a good excuse. I’ve seen the real deal in Finland, and though my demo doesn’t act (or look) exactly like aurora borealis, it does use the Circular Wander Class I blogged about last week ;) The code is pretty straight forward, the “trick” being that I take the y value of the “leader” (an instance of CircularWander), and cast that to the Z value of all the following particles. A little Blur, and voila. Then for lack of inspiration, I made it into a sound visualizer.

I used this random Image from Flickr as my source of inspiration:

Here’s a screenshot of the demo.

Here be the source files (without the .mp3, that would be file sharing?!)

I just added the code to the CircularWander.zip from the previous blog entry…

Hope you like it!

    Hi James, that’s strange… it should only “animate” on players 10 and up. Are you on a linux or so?
