Google maps zoom rocks ;)

Ok, this headline sucks, I know. But seriously: Have you guys heard about the google maps zoom 'hack'?
Well to make it short: It is possible to get a better zoom level than the one you can adjust by using the zoombar. The maximum zoom level you can get without our little trick is 19. The picture you see below has zoom level 23.
But how to get this?

1. Go to your location of choice.
2. Then click on 'link to this page'
3. Your browsers address bar should show now an URL with many variables
4. Within this URL is a tiny "z=XX" area
5. Now change this XX (normally 19 in biggest zoom mode) to 20, 21 or something like that.
6. You will see, you get a much closer look.
7. Et voila, your done :)

Btw: you can get the picture below after clicking on the following link:
