Easter eggs in Ubuntu

Question

I just found out about the free the fish easter egg available in Ubuntu:

1. Press Alt + F2

2. Enter this: free the fish

Are there any more easter eggs available in Ubuntu? What are they?

Answer 1

Here is another package that is just a joke : sl, standing for Steam Locomotive.

Just download sl and then run sl in a terminal.

It has been designed for people confusing ls and sl. See manual page for more exciting features!

Answer 2

Watch Star Wars in terminal telnet towel.blinkenlights.nl

Answer 3

Not gonna spoil it for you with a screenshot, but in a terminal try: apt-get moo

And then, if you have aptitude installed take a look at:

aptitude moo
aptitude -v moo
aptitude -vv moo
aptitude -vvv moo
(etc)

(Bonus: if you enjoy this then install cowsay for hours of command-line entertainment!)

Answer 4

For 11.04 and earlier:

1. Press Alt + F2
2. Type in gegls from outer space and hit enter.

Answer 5

I just found a quite funny mix between "cowsay" and "fortune":
First, install both cowsay and fortune

sudo apt-get install cowsay fortune-mod

Now, pass fortune as the argument for cowsay:

fortune | cowsay

A cow will now tell you something clever about life ;) Have fun!

Clicking on the fish with the mouse will make it go away, to get rid of it for good. you can type killall gnome-panel into the terminal. Also, as an easter egg, it is an undocumented feature.

ddate is short for Discordian calendar, which was the calendar of an old cult that worshipped the Greek god of chaos, Eris (thanks @tox123).

Unicode U+E0FF is displayed as the "Circle Of Friends" logo and U+F200 is "ubuntu" in the Ubuntu (typeface) on Ubuntu. Type: Ctrl-Shift-U, then F200 or E0FF in Gedit or Pluma. The characters are in the Unicode Private Use Area so they may display differently depending on which font you have selected. Here are both, they don't display on askubuntu.com, copy/paste to your regular text editor:

U+E0FF: 
U+F200: 
