A graphical user interface for displaying and magnifying a source image about a focos point comprises an image frame with a background image and a zoomed-in image. The image frame is responsive to user input. The background image is created from the source image, and fills the image frame. The zoomed-in image is created, by mapping at least a portion of the source image onto a curved surface as a texture, and superimposing a two-dimensional render of the resulting textured surface atop a region of the background image.
