I have been having fun making short video tutorials for our imagePlot visualization software which we released on 9/16/2011:
ImagePlot video demos on YouTube
The videos correspond to tutorials in ImagePlot online documentation and the use sample image sets which we provide with ImagePlot program. So if you want to follow tutorials, download ImagePlot.zip - it includes the software, sample sets, and theory and methodology articles.
To make the video, I use Snapz Pro X software for the Mac. I then upload the captured video to YouTube, and use its built-in annotation tool to add captions and text.
If you want me to make a video explaining particular features, just email me !
Happy image plotting,
Lev Manvich and ImagePlot team
