FlickrTools is a simple jQuery plugin that queries the Flickr API, and gathers all the images that match a certain tag. At some point, this can be expanded to query other properties in the API, but this is the simplest way to start. I use my flickr images as part of my home page hero, and as a rotating carousel of images. One of the nice things about this plugin is that the data retrieved from the query is reusable between both features on the site. The hero is custom jQuery, whole the carousel uses Slick.
SocialCards is a jQuery plugin that queries all of your social media outlets and gathers all of your recent content into cards and displays them on your own site. Currently it queries blog posts, Etsy, Flickr, Foursquare, GoodReads, Pinterest, and Tumblr. Soon to be developed are Facebook, Google+, Instagram, Twitter, and Youtube. It uses a masonry style based on the one I found on w3bits, that is configurable using CSS, included in the sample. The plugin integrates with the Google API for easy RSS reading, and with Yahoo YQL API for other more complex data.
