kmag 4:4.10.2-0ubuntu1 (amd64 binary) in ubuntu raring

 KDE's screen magnifier tool.
 .
 You can use KMagnifier to magnify a part of the screen just as you would use
 a lens to magnify a newspaper fine-print or a photograph. This application is
 useful for a variety of people: from researchers to artists to web-designers to
 people with low vision.
 .
 This package is part of the KDE accessibility module.
