<p>Atop Millikan library (a 9-10 story building visible from essentially all of campus) bright Christmas lights spell "MIT".</p>
<p>Well done : )</p>
<p>P.S. Some Calltech students have projected the mirror image of "Chang" below "MIT". The joke is that Tim Chang is the director of institute housing. Tim's picture appears below the sign.</p>
<p>It turned out that this particular event was due to some Lloydies, as was pointed out to me. So MIT hasn't gotten us back yet -- except for those DDOS attacks, which are a little below the talents of our comrades in the east.</p>
<p>So I presume the revenge is still in the making.</p>
<p>The MIT sign (originally a counter-prank on a prank by some members of Blacker) was only up for a couple days until the counter-prank itself was counter-pranked. The tree went up December 2nd or 3rd.</p>
<p>The MIT was replaced by the letters "TTB" although some believed it to say Pi-B. After asking several Moles, I learned that TTB stands for "Take That Buddy" (Although, Buddy isn't the exact word they said) which they apparently write at the end of a proof instead of QED.</p>
<p>The tree went up on Dec 2nd in record time, finishing at about 11:30. The tree should currently be in its full glory at night.</p>
