What I need is a program that is invisibly installed on any given target's computer that subliminally transmits a list of messages. These messages need to be able to be updated on a regular basis. The messages sent to the unsuspecting target need to be completely undetectable and flash randomly over the area of their monitor every 4 seconds for a maximum duration of 1/3000 of a second. If this is still detectable, it will need to be sped up till it is not.
As a bonus, I will teach the taker of this project a very effective audio subliminal technique, if they would like.
