I personally would have never made a public response to Richard Baumann, or any other people who wish to cause public unrest. People like that do not deserve anyone's time, and should be ignored, in my opinion; responding to them just gives them the attention they want.
QuickComposite
I'm working on a little app to allow you to take multiple images and composite them together, using Gimp-ish layer blending modes. It will use an XML based format for compositing instructions, and use floating point based calculations internally to preserve the data while blending multiple layers together.
