The part of the Ray and Maria Stata Center sometimes called "the twins" was brought to life on Tuesday with a pair of glasses,and a hat as part of a campus wide "Where's Waldo?" hack.

The word hack at MIT usually refers to a clever, benign, and "ethical" prank or practical joke, which is both challenging for the perpetrators and amusing to the MIT community.

Bryan O's Student Life Blog documents the hack around campus.
