intersticeThis is a very "clever" thing to do to people: http://www.wired.com/politics/security/news/2008/03/epilepsy
Of course I went googling for these images and found a couple. I also found this interesting tool: http://tools.webaccessibile.org/test/check.aspx which failed to detect the danger in the few images I found.
I did not have an attack, so I suppose I'm probably not epileptic. But I also noticed that the image was stuttering and unsync'ed due to my cruddy i810 video non-card. Anyway, it occurred to me that you could make custom video drivers for epileptics to use which wouldn't even detect dangerous flicker per se, but rather just control updating of any region of the screen so as to not fall into the danger zone (i.e. if there are significant oscillatory changes occurring at 4-55 Hz, throttle them down to 2 Hz). It'd be easy with these new killer graphics cards, but also sort of a wasteful way to use the processing from a technical and economic standpoint. I wonder how efficient you can make it.

Date: 2008-04-01 10:01 am (UTC)According to non-scientific television I saw some time ago, there are dogs which can be trained to detect the onset of epileptic episodes before they actually occur. Assume these dogs actually exist and are capable of that feat. So would one of these special dogs be able to detect whether or not an epileptic was about to click on malicious (or careless) hyperlinks?

Date: 2008-04-01 01:47 pm (UTC)From reading accounts on fora the past few days, I learned that photo-sensitivity epilepsy is only one type (wikipedia says it accounts for only 3% of epileptics). I am still suspicious of how a dog can predict epilepsy at all - the most believable thing to me is that less acutely-triggered seizures are preceded by a few minutes (?) of tremor or such, and that dogs notice this irregular behavior before their masters.
Apparently the dogs are trained as support, and the premonitory ability is just an occasional (and poorly-documented) bonus.

In addition to being able to do rudimentary math (indicated by pawing the ground) Chris could supposedly predict the future to some degree of accuracy. Reportedly he was a couple of days off on predicting his own death.
