It's very unusual to need to dynamically reference a local variable. In 
Ruby, local variables usually are highly, er, localized. An instance 
variable is much more frequently used in the way you describe, and you 
can access it, as Robert says, like so:

>> @foo = "the value"
  => "the value"
>> name = "foo"
  => "foo"
>> instance_variable_get("@#{name}")
  => "the value"
