I think this only works with Mozilla browsers; you be the judge.
In this timing test, you select a color from the drop-down menu, and press "Start" ... As soon as the background becomes that color, you must press "Stop" ... That time it takes between the appearence of the color, and your click ... is called your Reaction Time ... Waiting and not knowing is part of the test ... Remember now, click "Start," place your cursor over the "Stop" button, and wait until you see the the page turn the color you selected - then and only then should you click "Stop" - got it? - Enjoy.

A QUICKIE LESSON ON REACTION TIME
(most of this taken from wikipedia)

Reaction time (RT) is the elapsed time between the presentation of a sensory stimulus and the subsequent behavioral response. Reaction time is often used in experimental psychology to measure the duration of mental operations, an area of research known as mental chronometry. The behavioral response is typically a button press but can also be an eye movement, a vocal response, or some other observable behavior.

Reaction time is fastest when there is only one possible response (simple RT) and becomes slower as additional response options are added (choice RT). According to Hick's law, choice reaction time increases in proportion to the logarithm of the number of response alternatives; now y'all know what logarithms are. Reaction time is quickest for young adults and gradually slows down with age. It can be improved with practice, up to a point, and it declines under conditions of fatigue and distractions.
