Inverted program in / usr / bin / games

Question

Can I imagine it? I am sure that many Linux distributions have a program in / usr / bin / games that "fakes" text with a fixed width upside down. So for example, if you enter

hello 

he displays

 o773y 

or something like that.

But on the mailboxes I have logins these days, this is not so, and I can not find mention of this in google. Can someone point me to a copy of the program, please? :)

Answer 1

After some searching, I found it!

apt-get install filters
