If you're tackling a drawing/rendering problem that involves creating, manipulating, and then printing a 2D array, I've found it shorter character-wise to instead deal with a 1D array that you access with `$arr[$y*$width+$x]` rather than `$arr[$y][$x]`.

It's very simple and short to set up the array with blanks or zeroes with something like 
```
$arr=@(" ")*$width*$height
``` 

Half the reason for using 1D arrays is that initialization is much shorter.

To easily print the 1D array as a "2D" array to console, you can use a width-based regular expression to split your array into rows. This will join your array into a string, and then split the string into equally sized chunks and print them in order, effectively printing your 1D array as a 2D array:
```
-join$arr-split"(.{$width})"|?{$_}
```
