Just after class

After class, some people are staying behind for some final questions. This picture has a high angle (the photo being taken with the computers seen from above), layering and spacing (each row of computers being a new layer), and finally there is a leading line (the direction of the desks serves this purpose). This picture was taken immediately after class on Thursday, January 12.

(Unofficial, non-class) Bonus points if anyone can name who is in the picture.
