Double Poke in the Eye II was another piece that really caught my eye at the Neue Nationalgallerie. This work comes from American artist Bruce Nauman. It seems he's really into neon lights, many of his works use this medium. I just found this so whimsical!
I wanted two show both of the pairs of hands lit up, sorry if the shots are a little blurry. I know this is not exactly a sign, but I hope you'll indulge me. For more signs, take a look at Signs, Signs.
