A recent edition of the Brick Journal (issue 28) has a feature on building the Police Spinner car from Blade Runner. It also has some new photos of the one-off version that Lego built for designer Syd Mead.
You can find physical copies of the magazine in Forbidden Planet sometimes or download it from their site here. The rest of the issue is heavy with insights into the Lego Movie and the various character, vehicle and set builds behind it.
