Three unrelated-to-each-other Google easter eggs (may not work in all browsers):
- Search for [askew].
- Search for [let it snow]. (And after letting it run for a bit, click/drag inside the browser window for another neat effect.)
- Go to Google Maps in a desktop (non-mobile) browser, and request walking directions from Rivendell to Mordor. You have to select walking directions for this to work. The easter egg is in the yellow warning box that appears on the left, so if you don't see a yellow warning box, it's not working. (The actual map and directions are irrelevant.)
Oh, and while I'm here: this isn't an easter egg, but did y'all see the awesome interactive Stanisław Lem Google Doodle?
