Hello,
In-between working, going out and developing ToolTask I have just made the finishing touches to the first version of Pixel Picker.
In a nutshell, this software gets the Colour (or Color to non-UK people) that is currently underneath the mouse pointer.
I know that this has been done many times before but that hasn't stopped me from making my own version.
