Video Tutorial

Don MacAllister made on of his wonderful screen casts (video tutorial) on iVisualize.

He Shows Everything from how to install iVisualize, over how to use it to a step by step introduction on how to create your own visualization.

The video is available on screencastonline.com in different versions. A free version is available from the archive (it's numebr 54). You can also get a HD, ED, and iPod version of the tutorial for a nominal fee of $1.99 or if you are an Extra! member.

I suggest a paid version for higher quality and to support Don paying for the traffic for his wonderful project.
