We will be joined on Tuesday and Wednesday by two pyschologists, who will not only be conducting experiments into advertising, memory and product placement in TV programmes and on willpower (human guinea pigs very welcome!) but who will also be looking at the fascinating world of optical illusions.
One of the illusions we’ll be trying out tomorrow is the magic dragon. This toy, that you can make yourself in around 10 minutes, has no moving parts. So why does it appear to watch you as you move around the room?
Why not call in and take a look?
