Another case that is applicable is Williams Elec., Inc. v. Bally Mfg. (No. 82 C 2167) In this case, the copyrighted design of a pinball machine playfield was copied almost exactly.

In this situation, the look and feel can be claimed to be inextricably linked to the function and utility of the site by the same argument.
