The fun folks at Google now present for your viewing pleasure… Google Sets.
Enter in a group of things you know belong to a set and then click a button and Google predicts other items that might belong to that set each linked to a Google search for that word.
I played around with it, and found it to work pretty effectively. Some funny stuff, try putting in “walrus manatee dolphin” and click on large set to see someone unusual amongst all the sea creatures. 😉
Or you could try putting in “one two three four five” and see how Google counts!
