This site – Don’t Click It, is very interesting.
Basically, you don’t have to (and aren’t supposed to) click the mouse button at all (apart from the initial ‘click here’ at the very start) to navigate it. I’ve had a play around and it’s actually really difficult to try and stop yourself clicking, especially when there are buttons that you expect to have to click.
It breaks all the rules of interface design that we’re used to, and it is an interesting exercise in seeing whether you can resist clicking.
Have a play around!
