I thought those kids kitted together their own gear....
Depends on the goal of whomever assembled it. The article has this to say (I added the emphasis):
The GAMBIT Game Lab is part of Comparative Media Studies , the largest humanities major at MIT. Comparative Media Studies and the GAMBIT Game Lab have grown out of MIT's longstanding commitment to the study of media in fields as diverse as engineering, mathematics, filmmaking, architecture, and the visual arts.
This exhibit includes several of the games developed by MIT students in the summer of 2010, in collaboration with students from Singapore.
So while MIT does have an engineering department, the focus was actually on the software developed by er... software engineers who likely have little to no understanding of the underlying hardware involved. Or the students might have been in a time crunch and did not have the time to assemble the needed hardware from scratch and simply resorted to using off-the-shelf components.
Also, the games came from Singapore. So they might not have even have access to the hardware we have here. I dunno.
