Walking duck

Hi all,

Here a program of a walking duck on a 50x50 grid.

Rules are:
When cell has no color:
Duck will color cell yellow and move right.
When cell has yellow:
Duck will color red and move left.
When color has red:
Duck will color yellow and move right.

It turns out the grid is coloured quite frantic.

Quit amazing that the pattern shows randomness without the random function beiing used.
There are no fences at the borders of the field. The duck wants to leave the field and causes an "out of bound" error. :D

Yes indeed very random! I was hoping to see some symmetry.

I now have a slightly improved version, because it shows where the action is.
Colouring the actual position of the duck white makes it more clear.

Also changed the rules which leads to a duck that seem to want to 'grow' its playground!

I would call this one the yellow fence builder :-)

Portrait mode? May be the case, i didn't care. I'm a sloppy programmer.
Here is another modification: a high voltage fence is added, throwing the duck back into the field if it tries to escape.

Here is my contribution. I kept the enhancements by Dutchman, but restored the white circle (now filled) to show exactly where the duck Is moving. And now the duck has a quack, which fades away once he escapes. I really feel sorry for this little duck, as he seems to be in a real panic. Sometimes I feel like cheering when he escapes!

You will need the duck.mp3 attachment to make it quack. :P
