Google search views: map and timeline

Google has opened their Experimental Search to the public. The cool ones are timeline and map, and you can use them for any Google search (they work best for people, organizations, places):

timeline: use the search term "view:timeline"
map: use the search term "view:map"

Try these:

"dark matter" view:map
"bill clinton" view:timeline

The standard view is "list view" but view:list doesn't work. I tried some other views but didn't find any easter eggs ...
