Roulette Simulator

I would like to have a list of student names, and a command button, that when pressed, begins highlighting the names one at a time ( starting at the top, moving down through the list, then starting at the top again, moving down through the list again, etc etc) each time the time that each name is highlighted gets longer and longer, effectively like a roulette wheel.

Eventually, one of the names would remain highlighted.

When the command button is pressed again, the 'roulette' highlighting process starts again, and eventually another name would be highlighted.

I already have a 'random student selector' program operating that returns a student name randomly and without ever returning a name twice, but it lacks the drama and suspense this 'roulette' method might provide.
