Welcome to OmarVision! The OmarVision website is intended to show that programming is really easy and anyone can enjoy it. Sharing knowledge is just my way of trying to help creative minds explore their endless possibilites. The site has many, many sections which I have continually been trying to provide access to in a sensible organized manner.
