This is a little Off Topic. Philipp you can delete it if you want.

Okay, I am working/teaching myself on a little Google Maps project and need somebody help. Currently I try to do something similiar to this: http://gawker.com/stalker/
What I need to know: How can I create a <div> (or something) and with mouseover a pinup in the map highlights.
I hope somebody can help me.

Looks very on-topic! I searched Google Groups for [google-maps-api marker onclick] and found this in one of the posts:

<<I recently needed a way to have a checkbox add and remove a GMarker from a Google Map. This JavaScript will create a GMarker when the checkbox is true and remove the Marker when it is false.>>

Is that helpful...? More in Google Groups...
