Zoom Cursor on Hover

[jamesalmeida]

Would be cool if there was a built-in option to enable the cursor to be a Magnifying Glass with the Zoom + in it like they have when you hover over an img on Pinterest for example.

Tried using something like this but it doesn't seem to work:

a img:hover {
cursor: -moz-zoom-in;
cursor: -webkit-zoom-in;
cursor: zoom-in;
}
