My employer wants our company's facebook looking a bit flashier, he's directed me to some company pages that have some simple and effective apps. Unfortunately, I have no coding experience, and the in-house coders are busy making the things that the company sells. These apps we're talking about look very simple. i.e. one that displays a Twitter feed (http://www.facebook.com/inFlowInventory/app_207976986934), one that shows embedded Youtube videos (http://www.facebook.com/inFlowInventory/app_158587972131), and one that shows one large-scale image. (http://www.facebook.com/IncreaseYourLikesNZOnly/app_203351739677351?ref=ts). Is there any such thing as a pre-made app that does something like these, that I can simply plug in to our page?
