Jenny's Magic Eye pictures
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Jenny brings in a 'Magic Eye' picture book, featuring stereoscopic images, hidden in seemingly random patterns, which are revealed when the viewer looks at them in the correct manner. Alex displays a full-screen example of one of the images on screen, and insists that Greg try to find the hidden image. While Greg is looking at the screen, the photo of him reclining mostly naked on the floor (repeatedly used in Rhod Gilbert's prize task submissions, during series 9) is briefly flashed on screen. Alex reveals that the actual hidden image is of a steam train. Greg awards her joint last place, along with Mae.
