Blueprint at AppIconsDesign.com by Peter Mileno, This is a lot of detail packed into a small icon. I think this icon works with all of the detail. The lines on the paper and protractor may get lost as the icon gets smaller. The designer used iconic pieces. It looks like the piece of paper is a blueprint, which is iconic in a lot of places. The pencils and erases look a little flat, but that doesn't bother me. The desk background works well with the rest of the icon.
