Access analysis "Crazy Egg" to show where on the page was clicked

It seems that official service has not started yet, but expectation is large.
Unlike normal access analysis, it is a form to display on so-called actual page.
Crazy Egg - Coming Soon ...

It is quite fun to be displayed with such feeling when actually used.

You can see where well clicked at a glance


Also, it's also possible to see it in the form of a heat map, hot!


It gets more red and hot as it gets clicked frequently.
I am interested in access analysis, but I am afraid someone who is contradictory that I do not want to see numbers.
Is it easy to understand, is it harder to understand ... ...
