Site now viewable without flash

I've made some changes to the website that allows all devices to view the contents of the site including when adobe flash is not installed on the system. Many mobile phones and tablets do not support flash, including some PC's. Previously when browsing the website on those devices a gray rectangle was shown in the location where the flash animation should be shown, along with a notification that the flash plugin is not supported.

But now when the flash plugin is not installed the flash animations are automatically replaced by other more system-friendly content that can be viewed by nearly any operating system, even the word flash will no longer be mentioned. My intention is to build a website that does not cause any technical concerns to anyone.
