http://wiki.rubygarden.org/Ruby/page/show/ExampleDesignPatternsInRuby

The above URL used to have nice collection of design patterns and how
to implement them in Ruby. And currently...looks like the page is not
available.

Anybody has a mirror of the page? If yes...can  you kindly send the
link to the list.

There was only one Road; that it was like a great river: its springs
were at every doorstep, and every path was its tributary.

It is not the page, it is the whole site. So maybe someone will realise
that and fix it.
