I just got a chance to check out this web browser that I mentioned this morning.  It is incredible.  This is definitely not only beneficial for autistic children.  It is so much easier for any child to negotiate the web using this browser especially for children with special needs.  You can try the software out by just running it - you do not even have to download it completely onto your own computer.  The choices are limited as compared to the web but for starters this is awesome.  It will allow many children with disabilities to access the web more independently.  Check it out at www.zacbrowser.com.
