Transform a regular photo into a high-tech artwork made up of blocks and connectors resembling a circuit board.
First, we'll create convert the image to blocks using a combination of Photoshop filters.
Open a photo you would like to edit. We recommend using a high resolution image of at least 1000x1000 pixels. It is also fine to upscale a low resolution image before using this effect.

Duplicate the layer (Layer> Duplicate Layer or Ctrl+J).

Activate the top layer and apply a Mosaic filter (Filter> Pixelate> Mosaic) with a cell size of 16 square.

Apply a Find Edges filter (Filter> Stylize> Find Edges).

Apply a Median filter (Filter> Noise> Median) with a radius of 2 pixels.

Apply a Minimum filter (Filter> Other> Minimum) with a radius by 4 pixels.

Finally, invert the current layer (Image> Adjustments> Invert or Ctrl+I).

Now that we have the blocks created, we'll add a simple outline around them.
Duplicate the top layer (Layer> Duplicate Layer or Ctrl+J) and change the blending mode of the new layer to Screen.

Apply a Find Edges filter (Filter> Stylize> Find Edges).

Invert the current layer (Image> Adjustments> Invert or Ctrl+I) and the outline should blend into the image. One last thing to do is to reduce the opacity to 25%.
We're almost done with the effect. All we need to do now is add the connectors. This is a simple process using a few Photoshop filters.
Duplicate the Background layer (Layer> Duplicate Layer or Ctrl+J) and move it to the top.

Apply a Mosaic filter (Filter> Pixelate> Mosaic) with a cell size of 16 square.

Activate the new top layer and apply a Median filter with a radius of 8 pixels.

As you might have guessed, we'll now apply a Find Edges filter (Filter> Stylize> Find Edges).

Finally, invert the current layer (Image> Adjustments> Invert or Ctrl+I) and change the blending mode to Screen.

This step is optional. If you would like to colorize the final results, follow this step:
Add a new Hue/Saturation adjustment layer (Layer> New Adjustment Layer> Hue/Saturation) as the top layer. Checkmark Colorize and apply your desired color settings. Here are the settings I've used for this step:
Colorize: Checked
Hue: 100
Saturation: 100
Lightness: 0
