And http://thebest404pageever.com/swf/AcidTripInaCan.swf for some real mindfuck, phychedelic not even needed. (may need a refresh to start after opened)
I would strongly advise against watching that. You see, psychedelic drugs don't create addiction which means they are safe to use, isn't that right? Wrong! They don't start addiction, physical or even psychological in most cases but if you have family history of mental disorders psychedelic drugs can bring it to the surface. Anything can, but certain things have stronger effect on it and psychedelic drugs are one of those things.
Same goes for that video. It could induce epilepsy in those who suffer from it, but it is can also activate underlying condition. Therefore, it is better being safe than sorry. Especially considering there is no special joy coming from watching that, unless you enjoy stupidity which I'm sure you do.
