• Do design your product with unique branding and logos.
• Do feel free to use names or logos for the purpose of labeling our sites within your product, as long as use of such logos could not be confused with the branding or endorsement of the product itself.
• Do not copy the look and feel of our products.
• Do not include elements of our network that are not user-contributed content (i.e. no copyright material).
• Do not use our name, logo, or service to promote or allow fraudulent, abusive, or otherwise illegal activities.

If your [app] looks enough like one of our sites to confuse a reasonable user, you've crossed the line. All image files on the site are copyrighted, unless sourced from somewhere outside the network (ie. in questions/answers), so I wouldn't just lift those.
