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).
