Pokemon harmful to your health?

While learning to program rollovers for a web site, my student Greg told us of a Pokemon episode that had caused about 10% of its viewers to suffer seizures. It had 6 seconds of red and blue screens flashing quickly back and forth.



This means we are responsible for the graphics we put out on the internet. If we want to be seen and heard, it doesn't make sense to hurt our followers.



Are there other examples of things you have seen on web sites that were irresponsible?
