There are many buildings in LA which were designed after
Blade Runner and which seem to at least be partially inspired by the movie.
The most impressive one is actually the Caltrans Building, right across the street from City Hall. It was designed by the Morphosis architecture firm, and is partially skinned with photovoltaic cells that provide 5% of the power for the building. It is also liberally shot through with neon.
I should put the US Bank/Library Tower (it is right next to the Central Library, hence the name) on the LA Tour I put together. Now that I discovered this thread I can see the resemblance, and perhaps a bit of
homage as well. Incidentally the building was built as the First Interstate Bank building. Long after the bank got sold it still had the old logo.
