Create a binary tree

I need to create a binary tree like structure of directories using shell script... does anyone know of any algorithm for this ?

i tried doing a recursive algorithm
Code:
function CreateDir
{
   level=$1
   dirname=$2

   mkdir $dirname/sub1/
   mkdir $dirname/sub2/

   let level=level-1

   if [ $level -gt 0 ]; then
      CreateDir $level $dirname/sub1/
      CreateDir $level $dirname/sub2/
   fi
}
CreateDir 3 testdir

the testdir exists already. the problem is it is not producing a balanced binary tree, it seems to go only one way...if someone can find the mistake and correct it, that would be great too

ps:. this is not a classroom question or something like that, if u have an algorithm that does not use structure, etc.. that would be great too..

thnx in advance

NAME
shtool-mkshadow - GNU shtool create shadow tree using symlinks SYNOPSIS
shtool mkshadow [-v|--verbose] [-t|--trace] [-a|--all] src-dir dst-dir DESCRIPTION
This command creates a shadow tree of src-dir under dst-dir by recreating the directory hierarchy of src-dir under dst-dir and by creating the files of src-dir by linking them into the corresponding directories under dst-dir via symbolic links. When src-dir can be reached via relative paths from dst-dir, relative symbolic links are used, too. This high-level functionality is originally designed for developers to create copies of source trees. OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. -a, --all Really shadow all files and directories in src-dir. Default is to skip CVS related files and directories, backup files, object files, etc. EXAMPLE
# shell script shtool mkshadow -v -a . /tmp/shadow HISTORY
The GNU shtool mkshadow command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later revised and taken over into GNU shtool. SEE ALSO
