With Flash you can do more than just displaying videos. You can create stunning visual experience and offer your visitors incredible user interaction. Although Flash is definitely not the favourite medium for usability and accessibility advocates, it has its advantages and it empowers the Web with functionalities which make it an incredibly interactive medium.
With Flash designers can achieve results which simply aren’t possible with (X)HTML and CSS
The results can be creative, impressive, beautiful and fascinating. Under two conditions: 1) if designers find the right mixture between graphics, animation, video and sound and 2) if designers follow the guidelines of usability and user interaction.
However, since there is a number of things that can go wrong in Flash, it’s easy to get it wrong. In fact, there are thousands of examples where it is the case. In Flash any experiments with navigation and layouts are possible and in most cases it’s extremely hard to find a creative yet intuitive approach. Flash is commonly used by designers, agencies, advertisers and interactive web sites, and not on the sites where simplicity and quick access to information are important.
