Turn any photo into a dot grid artwork with these Photoshop actions. You'll get great results with dots that change size. They get larger in brighter areas and smaller in darker areas. Free download available.
The result should be similar to this:
Grab the Brush Tool (B), reset your brush settings, and make your brush rounded. Set the Hardness to 0%, Opacity to 100% and Flow to 5%. Pick color #f8ff7c, create a new layer above those triangles, name it "light1." Change this layer's Blending Mode to Overlay. Now start with a small brush, then add bigger and bigger dots in this place. Switch to white color and repeat the same process, but on a new layer (with Overlay Blending Mode).
You can apply those triangles and lights to every spot of this design, it's adds a nice touch of abstraction.
