Make a cute little Linux-esque penguin wallpaper with this detailed, step-by-step tutorial. Create a new file with
1024x768 px and
72 dpi and paint it in black color, the way it is shown below:

Select now this instrument

and try to outline a penguin?s arm.

Fill 0% on the layers

Apply this instrument

now to draw the inside part of the foot.

Fill 0% on the layers and set the
Opacity on 80%.
Blending Options-Gradient Overlay
Gradient?s parameters: 
Make use of the previous instrument to represent a flare on the upper part of the foot.

Fill 0% on the layers.
Blending Options-Gradient Overlay
Gradient?s parameters: 
For your convenience now we should merge down in a group all the layers composing the penguin?s foot.
Make a copy of this group then and apply
Free Transform selection to turn around the group on
180 degrees vertically.

Now we have to put together in a group both groups of the feet.
Make a copy of the new one and use again the
Free Transform selection to turn it around and compress it also vertically.

Select after the last operation a brush having blurred edges and grey color and apply it to create on the picture the effect of flatness.

Make a copy now of the new represented layer and apply again the usual option,
Free Transform, to turn the copy around on
180 degrees. We?ll make the changes also on its parameters:
Fill 0% on the layers.
