OK, another update for the cursor library and I think you'll love it.

Cursor previews on the cursor set and cursor detail pages are now animated and they are placed over a cross-hair to show you, where the hot spot is.

The previews are using the animated PNG (APNG) format that can, unlike .gif, handle smooth transparency. Hence a web-browser supporting this format is needed. Currently, that is either Firefox or Opera.

Browsers like Internet Explorer 8 or Google Chrome (or other Safari-based browsers) do not seem to currently support APNG and you'll see just the first frame of the animation. I'll let you decide how to deal with that...
