Oscillating chemical reactions

I don't know if you've reached this point in your class, but I always thought these were interesting. Basically the setup is that one reaction produces another series of reactants which then go on to react as well, ect, until the first set of reactants are produced and the reaction then cycles. When mixed with indicators, you can have a solution that occilates in color on a certain time cycle (good eye candy for the parents, and easy enough to produce).

I found this site that has a some of the reactions as well as an animation of the color changes about 1/4 down the page:
