perhaps more of a weighting system on proper names and whether it’ll return copyrightable material, strange what works and what just doesn’t.
“lisa frank” doesn’t work, but “a clone of lisa frank” does. “deiter rams” doesn’t work, neither does “a clone of deiter rams”, “facsimile”, “design language”…
Finally got something joyful when asked to create a chess-set inspired by "rooks". Least-playable chess-set ever :).
