Be sure to check out "Bluerain" before it leaves this Sunday for the London School of Economics Library.

What is it, you ask? Well, aside from being totally awesome, it's an art installation featuring over 23,000 LEDs that "make up a marquee of alien hieroglyphics." But what does it say? According to Curbed, "the lights are a cascading flow of record titles, recent library acquisitions, and current online searches conducted within the library to the public outside the building."

We love this. We want more of this. We demand blinky, blue lights on the sides of all San Francisco Victorians.

Word is there will be some sort of reception for the piece at 6 p.m. on Friday. "Bluerain" is located at the back of the bank parking lot on the corner of 16th and Julian, near Valencia in the Mission.
