Draft of a PNG logo.  White background (for printing on T-shirts).

This is some kind of a 3D bar graph, representing the Adam7 interlace
scheme of PNG.

I am not quite happy with the colors.  The texture is basically white marble
with black veins.  The red and green colors are caused by the illumination:
there is a white light source in the middle, a red one at the left, and a
green one at the right.  I tried using white ligth sources only, but the
image looks boring, and it is more difficult to recognize the bars.
