The local.ch location pages contain many nice information about every city and village from Switzerland. Since putting the regional news online, I regularly look at the location page for Olten.
I’ve now created a Greasmonkey script which - once installed - automatically jumps from tab to tab every five seconds.
You can get the script. When you open that page Greasemonkey will ask you to install the script. I’ve tested the script both with the original Greasemonkey as well as with the Safari implementation GreaseKit.
