Magic Eight Ball with the Raphaël JavaScript Library (1.5.2)

Wrigley’s Magic Weight Ball is my first project using the Raphaël JavaScript Library and it just went live. I used Raphaël JS version 1.5.2 which you can download from GitHub. The project requirements came through as only being an iPad version that responded to a shake event. Getting to use a new technology for a front-end project where you only have to support one resolution and one browser is an excellent opportunity to try new things. I knew in the back of my head that they would want a non-shakeable static version as well but they just didn’t ask for it yet. Internet Explorer still came into consideration when I was evaluating technology solutions because I was certain it would come up eventually.

When I saw the Nissan Leaf site I was blown away by the heavy JavaScript animations being used. It really reminded me of the early Flash animations and sites in a way. The Hacker News submission I saw the site from pointed out that the animations were being handled by the Raphaël JavaScript Library. This was still fresh in my mind when I got this project so I loaded up the Raphaël demos pages in a ever browser I test on, IE6-9, Safari, Firefox and Chrome and they all worked! This was the library for this project.

I finished up the iPad version of the site which requires iOS 4.2 or higher and was pretty happy with the results. It responds to a full shake event to give you another tip, the tip will bob lightly in the water when moved a little bit and the tip orients to the iPad. When the tip is touched it provides a little modal with more details. The site even supports landscape and portrait viewing.

About half way through developing the iPad version the email I was expecting arrived. “Oh no!” they said, “We need a static non-shakable version for desktop users to visit.” I was already prepared though. When I though about a desktop version I first defaulted to Flash but I wanted to give Raphaël a try first. With a IE6 PNG alpha transparency fix and a small work around for IE to get the Raphaël image src it was up and running on the desktop.

You can visit to see the result and if you happen to hit the page in an iPad you will get a slightly modified version that still responds to the shake events, always giving the best experience possible.

The weight ball interface itself is a series of 3 layered PNG images. The top most image is a 24bit eight ball and the rest of the tips, triangles and back black images are all 8bit PNG images with the a properly picked matte color. The total site size was reduced as much as possible and the designers loved the look. I reduced the number of colors where ever possible and used a pattern dither, it really seemed to look the best even though it bumped up the file size a bit.

For this animation interface the Raphaël JavaScript Library was a perfect fit and I was able to provide a cross platform and cross browser experience that I was very proud of.
