[AP] Is it possible to pixelate with spaces or 'gutters' similar to the grid spacing options?

[McPhearson]

I want to pixelate an image, then take each pixel/square and shrink them from the center of each pixel/square, leaving a gap/space/gutter in between all the pixels/squares. Is this possible to achieve?

Thank you in advance

If you are using Photo try the halftone filter. 

A Pixel is a pixel and will be only one colour. This is due to the fact that it has no subdivisions.

This looks like it will get me what I need, thank you much
