This only works with simple animations and is still quite resource heavy on the iPhone. As PCWorld points out, As a JRE extension it runs natively inside the iPhone’s Safari browser, however it will only work on sites that have specifically incorporated the Gordon code. Reports indicate that a static image presented in flash will peg an iPhone at 100% CPU, so it’s not quite ready for browsing YouTube via Safari just yet. It does support the full feature-set of Flash, including interactivity and animation, but full-Flash sites may not be viable on mobile devices for some time. Take a look at some of the demos – they work on the iPhone as well. Interestingly, running the demos on my MacBook Pro, I saw less CPU usage with the Javascript version than I saw with the Flash version. It might make sense for Adobe to incorporate this type of system so that developers can get their animations to work on all web-enabled devices. The downside is of course that fewer people will need Flash on their computers – which flies in the face of everything they stand for. So is Gordon, as iPhone processors get faster and faster, the long term solution to Flash on the iPhone?
