Masonry + infinite scroll + insert content

[chechu]

Hey all,
I have a site that has exactly the features I'm looking for, but the loading is amazingly slow: http://www.inspiredpersonality.com
Does anyone know of a template (html or WP) that has these functions: masonry, infinite scrolling, content not popping up but moving in between the rest ?
Thanks!
