Looking for a scroll gallery with these features in a WP plugin...

Client is liking this picture scroll gallery (is not a WordPress plugin):

They want one that scrolls slowly & smoothly back and forth when hovered over. Would like each image in the gallery able to enlarge to its native horizontal or vertical orientation when clicked on. Bonus if it also has a slideshow that can be stopped and started at any point, and easily revert back to clicking on each image for viewing.

Aesthetically, would like the thumb gallery as a continuous strip, ie, no spaces between images, as in the linked demo, but this isnt essential. The thumbnails would be approx 100 pixels high x the proportional opposite dimension. Images would display at approx 500 pixels high x the proportionate opposite dimension.

Thanks!
