iHallucinate is in the store now, check it out! http://appshopper.com/entertainment/ihallucinate Ever wanted to hallucinate? Of course you have! This unique app lets you do just that, by flashing patterns of light through gently closed eyes and stimulating the optic nerve in a way that alters the mind's natural oscillations. This can cause the viewer to feel surrounded by colors, shapes, patterns and more. The effect can be intense, but is easily canceled by simply opening the eyes. This does not work for everyone, but 4/5ths of those who tried it while in beta saw it very quickly. Relax and allow yourself to see it- don't try to force it. This effect and its cause is well documented, and is similar to the effect the famous Dreamachine produces. Three easy steps to tripping out with iHallucinate: 1) Crank brightness to max, launch iHallucinate 2) Put thumb on slider and iPhone up to closed eyes 3) Slowly adjust slider until you see colors, shapes, geometric patterns, etc. Certain people respond best to certain frequencies so we designed the slider to easily and intuitively find the best one for you. Works best when brightness is set to highest in a moderately lit room. Try with music: iHallucinate is designed to let your iPod tracks play in the background for an even better experience. Try with lower brightness settings in a totally dark room for different effects. WARNING: Use at your own risk. A very small percentage of the population may be adversely affected by flashing light effects.This app should not be used by anyone with epilepsy, other photosensitive conditions or nervous disorders. By using this application, you agree that you do so at your own risk and that we take no responsibility for damages directly or indirectly caused by the use of it.
It really does work, the phenomenon can be read about at: http://en.wikipedia.org/wiki/Dreamachine While we were developing I found that 4/5ths of those who tried it could see it, with the occasional person not seeing anything. I'm not sure why it would work for most people and not for some, but that's why we developed the slider so you can try different frequencies in hopes that one of them will work for you. But of 300ish people who've bought it, I've only heard from two who it hasn't worked for.
