Granny Muriel Santilli , 79, answered an advertisement in her local paper and found herself entering an extraordinary world where her wildest dreams came true. She was actually inside the brain of a computerised simulator where impossible things happen all the time. Soon millions will be able to follow Granny into strange simulated worlds. Scientists have invented a home simulator that anyone can use; it will be in the shops next year. They say it will be even more popular than television! Narrated by Anthony Clare.
