#ASCII Art of the Day Series

My new found love for ASCII art has lead me to a lot of good (trivial and non-trivial) ideas for ASCII ART challenges. Here are the ideas :

***2. Flow Snake***

I came across this really nice snow-flake like ASCII fractal by Michael Naylor <sup>[citation needed but not found]</sup>. Just like a fractal, it grows exponentially in size with each order. Below are the details about the construction and the examples for various orders:

*Order 1 Flow Snake*:

 ________
 \ \
 \____ \
 /
 ____/

*Order 2 Flow Snake*:

 ________

 / ____ \____ \ \/
 \ \ \ / /
 \ \ \____/ / ____

 \/ ________ \/ /

 \____ \____/

*Order 3 Flow Snake (reduced in size for feasibility)*:

**Construction**

Consider the order 1 Flow Snake to be built of 7 edges and 8 vertices (labelled below):

 4____5____6
 \ \
 3\____2 7\
 /
 0____1/

Now for each next order, you simply replace the edges with a rotated version of this original order 1 pattern. Use the following 3 rules for replacing the edges:

**1** For a horizontal edge, replace it with the original shape as is:


 ________
 \ \
 \____ \
 /
 ____/


**2** For a `/` edge (`12` in the above construction), replace it with the following rotated version:

 /
 / ____
 \ / /
 \/ /
 /
 ___/

**3** For a `\` edge (`34`and `67` above), replace it with the following rotated version:

 /
 / ____ 
 \ \ \
 \ \ \
 \ /
 \/

So for example, order 2 with vertices from order 1 labelled will look like

 ________
 \ \
 ________ \____ \6
 \ \ / /
 \____ \5___/ / ____
 / \ \ \
 4___/ ________ \ \ \7
 / \ \ \ /
 / ____ \____ \2 \/
 \ \ \ / /
 \ \ \3___/ / ____
 \ / \ / /
 \/ ________ \/ /
 \ \ /
 \____ \1___/
 /
 0___/


Now for any higher order, you simply break up the current level into edges of lengths 2 and repeat the process.

**Challenge**

* You have to write a function of a full program that receives a single integer `N` via STDIN/ARGV/function argument or the closest equivalent and prints the order `N` Flow Snake on STDOUT.
* There should not be any leading spaces which are not part of the pattern
* There should be either no trailing spaces or enough trailing spaces to pad the pattern in a perfect square.
* Trailing newline is optional

**Fun Facts**:

* Flow Snakes is a word play of Snow Flakes, which this pattern resembles for order 2 and above
* The Flow and Snakes actually play a part in the pattern as the pattern is made up of a single path flowing throughout.
* If you notice carefully, the order 2 (and higher as well) pattern comprises of rotations of order 1 pattern pivoted on the common vertex of the current and the precious edge.

**Sandbox notes**

Should I make the edge size 1 instead of 2 ? (So that the order 3 example is a valid one and order 1 and 2 are double sized)

***3. Random Ants***

This is still a bit hazy but the challenge would involve making random ants out of the following ants:


 \_/
 '-0-'
 --0--
 .-0-.

 \_/
 '-0-'
 --0--
 .-0-.

 \_/
 '-0-'
 --0--
 .-0-.


 \O/
 '-O-'
 /o\

 '-O-'

 '-O-'
