Hi Maarten,

You could grab the dbox code from Steve Lime's DHTML Landview interface:
http://www.dnr.state.mn.us/maps/landview.html

I think the workshop demo download also contains the dbox code:
http://maps.dnr.state.mn.us/mapserver_demos/workshop.zip

There is a presentation on dbox at:
http://www.omsug.ca/dl/osgis2004/box_presentation.zip

I currently use a variation of this:
http://gis.nacse.org/temp/zoombox.js

Take a look at the thread from March 2005 entitled "Rubber-Band Box
Zooming," which contains most of the info above.
