The Reaction Timer: 
This  is inspired from those competetive times Ujjwal & I had while indulging in this game during the computer practical classes(of course behind Father Paul's back!) The idea is to press any key asap after a beep is heard from the computer. The least time possible scientifically is 0.1 secs. Let's see how close you can get to it!!
(Out here instead of a beep sound, I've included a simple start...wait...stop sequence.)









P.S: I've intentionally added a disturbing background to ....  DISTURB YOU YAAR!!

My lowest average has been around 0.3 till now. What's yours???
