From IAN SIMMONS
The ‘Holister Effect’ sounds like the effect produced by one of the exhibits
in ‘Science Alive.’ the hands-on science centre here at Snibston Discovery
Park. In our ‘Blood Vessels’ exhibit, the user rests a small light on their
closed eyelid and wobbles it to-and-fro, producing just the effect
described – sharp black blood vessels against a pink background, these
being the blood vessels running across the retinal surface.
