Hi!
As per Paul's suggestion to try to modify the perspective of María's
mosaico designs to make it vibrate a little less with icons on the
desktop, I did some experimentation today in Inkscape with perspective.

The source SVG is in the directory as well. The two gimp ones I just
poked around at in the gimp, I didn't do too much with them so I didn't
bother uploading the source.
