Mosaiqy is a jQuery plugin for viewing and zooming photos and images in a Mosaic-like grid interface.
The images are displayed inside randomly moving columns and rows where CSS3 transitions are used for the animations.
Once a thumbnail is clicked, the original version is loaded inside the gridwith a nice slideIn/Out effect.
It retrieves images from a JSON/JSONP data source which makes integrating with image hosting services pretty easy and there are already demos for Flickr, Instagram and Panoramio.
Mosaiqy has multiple configuration options like the speed of transitions, delay between each, number of columns/rows, looping on/off and more.
