Hi, I happen to have a MIS degree. What you could do for that cake is do the computer theme. You could do a floppy disk, or little bugs (to indicate bugs in the software, lol) or little mice (to indicate a computer mouse)
In the 1997 yearbook they have a cake that has little Wilton candles that are shaped like computers, and then little mice mice all around. It's very cute.
Go to the wilton site for cake ideas
In the search box type in Graduation. There are plenty of ideas to spark your creativity.
You could do something really simple and modern and then make up little graduation hats or diplomas (or just buy them) and place around the cake.
Something along these lines

Either way, that website has many ideas!
