Hi Nicky, Below is the link to a web page and the text from an article written by Dr. Mark Magennis from the CFIT and NCBI. It is very informative and gives you a point of reference about what you need to consider when designing accessible Powerpoint slides. After having read it myself I thought how I would have never considered accessibility in a powerpoint presentation before. http://tinyurl.com/34a4zf.
