For all those who are not able to get up from thier morning sleep where alarms are no use for them, there is a new product called Pattern clock. This clock won't turn off the alarm unless you repeat a Simon-like pattern of lights by pressing a series of buttons. This alarm clock will defintely wake you up and the side effect would be driving you crazy as a part of the process. I gotta buy one for me!

PS: I heard from some sources that people just pull the power of these types of clocks to stop them from screaming. There were also some instances of breaking the clock in heights of frustation.
