My department's Christmas party is coming up, and I have the duties for seating arrangements. To make people mix and mingle a little more than usual, I wish to create a simple program, which draws two numbers at random from a list of participants, every X minutes. This will prompt the two corresponding participants to swap seats (actually, they will meet at the front of the dining hall, pour a glass of snaps, say cheers, and then swap seats!).
My questions is, can this be done using MATLAB? Ideally the numbers should be shown on a Christmas image background.
