Just read about this browser a man had made for his grandson, who has autism. It is called ZAC Browser, for Zone for Autistic Children and he has made it free for those who are interested. it is also useful for those with other autistic-related conditions, like asperger syndrome.
Check the site out and see if it could be useful for anyone you know. They may not know about it...
