There is a special logo on Google UK for Stanislaw Lem. He is known best for The Cyberiad, series of humorous short stories from a mechanical universe inhabited by robots.
The logo is incredibly interactive. The designer, Marcin Wichary posted on Google + many of the easter eggs in this Doodle.
- The brick that falls out from the first robot when it explodes is a brick drawn by Lem himself. (Everything else is drawn from scratch by +Sophia Foster-Dimino inspired by the style of Daniel Mróz.)
- The wave in the second level spells something in binary/ASCII.
- Some of the eyes of the monster (Pugg) in the second level will follow your mouse – unless, of course, you are on a tablet (I agonized a lot about it. Eyes following a mouse pointer is such a cliché.)
- Clicking on the bird makes it fly elsewhere (if it's allowed at that moment).
- Clicking on the cat will make it go away. It will eventually go away on its own, but hey, you didn't really expect to be able to control a cat, right?
- After some time of inactivity, the bird might sit on your mouse pointer.
- In the second level, you can see an actual Polish scientific satellite LEM flying in the background.
- If you finish the doodle twice, at the third time you will see something extra in the finale, based on another story we didn't have time to squeeze into the doodle.
- There are different N items depending on how many times you played the game, and which language you're using.
Here is a short video of it in action:
Google US has a logo for Thanksgiving, so this is only on Google UK today.
