[racket] Flappy Bird in Racket

Hi All,

To amuse myself I have written a little Flappy Bird clone in Racket.
I have attempted to keep the programming style very simple.

https://github.com/soegaard/flappy-bird/blob/master/flappy-bird.rkt

I do not intend to add features myself, but I will gladly accept patches.

Btw - I have inserted images directly into the source, so open the
document in DrRacket to what it is all about.

Enjoy,
Jens Axel
