In Park Slope, Brooklyn there is a lamp facing out of a window on the third floor of an apartment building located on the northwest corner of 7th Ave and 1st Street... and you can control it.

Step 1: Go to Park Slope, Brooklyn and make sure you are facing the window described above.

Step 2: Open foursquare on your mobile phone and check-in to the location called "LampSquare" to turn the lamp on.
