1. Create
a new 165x165 pixel document with a resolution of 100 and name it Mini-Techno.
Now press D then X and
fill the document (with White). Now apply a noise
filter with settings [Amount: 300%, Distribution: Gaussion, Monochromatic:
Checked].

2. Now apply a mosiac
filter with settings [Cell Size: 12]. Depending on the size of your
image or how large you want the lines you may want to change the cell size.
3. Next, you
glow
the edges with settings [Edge Width:
2, Edge Brightness: 10, Smoothness: 5].
If you want more smooth edges on the lines just make the Smoothness setting higher.

4. Now you
can add color to the image by, creating
a new
layer and filling it with a color of
your choice. Then set that layers blending
mode to 'Color'. There you have it, a neat
little mosiac lines.
