Interactive one already exists in the official dists.  Just get any 
binary/(or get the source and make), then try the below:

$ ruby -r 'irb/main' -e IRB.start [ENTER]
irb(main):001:0> def fib(x)
irb(main):002:1>   x < 2 ? 1 : fib(x-1) + fib(x-2)
irb(main):003:1> end
nil
irb(main):004:0> fib(3)
3
irb(main):005:0> fib(5)
8
irb(main):006:0> exit
$
