- http://interactjs.io has some demos showing drag and drop, gestures,

ienrtia, snap and some other things.

- The [html & svg demo](http://interactjs.io/repo/demo/html_svg.html "drag, drop,

resize and gesture demo") shows div elements which can be dragged and

dropped onto each other and resized by dragging the botom and right edges. The

yellow elements are SVG elements (these won't show up on IE8).

- [star.svg](http://interactjs.io/repo/demo/star.svg "editing an SVG document")

demonstrates interact.js being used within an SVG document.

- The [snapping demo](http://interactjs.io/repo/demo/snap.html "Oh snap!") shows

how flexible the grid and anchor snapping system is and it's pretty fun.

- This [blog post on path

snapping](http://taye.me/blog/interact-js/snap/2013/09/29/interactjs-path-snapping.html)

demonstrates and graphs some interesting path snapping functions.
