Change the speed of the blinking bulb to a frequency you like, adjust the brightness of your screen to a maximum, make the room as dark as possible, and position your eyes very close to the screen. The hallucinatory effect is best experienced with closed eyes. Should not be used by people prone to epileptic attacks. If the blinking bulb does not appear properly on your machine, you may need to download the latest Java Plug-In for your web browser.
