2 image left to right slider

Anyone knows the name for this plugin?

I mean the image transition? To slide the image from left to right and reverse. I know this page wasn’t made in wordpress but i was wondering if there is a plugin that does the same thing?

I tried googling it but i get regular sliders instead..

Thanks in advance!
