Did I miss the link to the example showing it in action? Or is that left as an exercise for the student?
---There's no demo because it behaves exactly like the Masonry example for infinite scrolling and Pinterest.--- Screw it, I added a link to the example. It's on tindie.com.
I'm looking at tindie.com and I see the inifinite scroll but I don't get the need for masonry. All The blocks appear to be the same width and height.
