Social Sharing Bar for Mobile Based Websites?

Check out this great mobile floating social sharing bar that MSNBC uses on their website.

(Make sure to view on iPhone/iPad/Android)

MSNBC - Computer Glitch Blamed in San Diego Fireworks Boom that Went Bust - I’m a new member and cant post a link.

Does anybody know of a script that can be downloaded to use this on my own mobile based website? I’m currently using Cubiq’s Add to Home Screen which is pretty amazing to keep the app on the user’s phone.

any help?

Didn’t find any. I only use responsive blog themes and that does display social sharing button properly
