This sounds a lot like the story there was about a supposed child prodigy (I think she was 5 or so) who produced paintings (made almost believable because it was the variety of paintings that are lots of paint splashed on canvas). Her parents would never let anyone see her painting though. Finally, one of those TV news magazine type shows convinced them to set up a video camera in their home to tape her painting since they claimed she wouldn't paint if people were watching. Contrary to the parents' claims that she would just sit down with paints for hours and not stop, the tape showed her parents spending an awful lot of time trying to urge her to paint, pointing to the canvas as if to give her instruction of where paint goes, etc. The final product looked little different than an average child's finger painting. A psychologist watching the tape said she showed very age-appropriate behavior and skills, but nothing that would indicate she had the passion or focus or exceptional skill that a prodigy would require. The overall conclusion was that her parents (likely her father) were doing the paintings for her (or at the least, finishing them for her to make them look professional).
