SalarO has been using Adobe Flash for over 7 years. However, in the last 2 years, since Apple decided to stop support for Flash, we are moving all the graphics elements into jQuery type animations. Flash has also got other issues, due to accessibility and usability flaws, but we do use it for limited interactive/animated elements within your site to help stimulate more mundane designs.
Whilst Flash gives us full creative control in to help enhance your message through your site, resulting in a unique and memorable end-user experience - the jQuery is much more restrictive in animation. We therefore, may have to translate complex aspects into video and incorporate it in our jQuery animation.
