A Flikr account called Jon & Karen's Photostream, which recently joined my Flikr group pool Lost New York City, has some nice hallucinogenic photos of Manhattan and Brooklyn neon signs I love or have loved, including Waverly Restaurant, Nathan's of Coney Island, the late Armando's of Brooklyn Heights, and, yes, our dear, departed McHale's.
Don't know how they achieved the photographic effect. Probably a simple trick that is nonetheless mystifying to me. Nice work, though. If they actually hang out at the places they photograph, I account Jon and Karen fine people indeed.
