[Plugin: NextGEN Gallery] Identify this plugin?

Is there a nextgen plugin to achieve this effect of a horizontal scroll, as depicted in this screenshot? http://img524.imageshack.us/img524/4289/screenshot20110215at950.png

Took a screenshot of the code in case anyone recognizes it:

Any help would be greatly appreciated.
Is it something to do with this?
