Does anyone know plugins used?

Hi,
Does anyone know what kind of plugins are used on this website ?

Which plugins are used to make:
– pictures ( large and small) angles rounded?
– to have a text “The Big Bang theory” in sort of transparent tab on the bottom of large picture?
– to change color of the background in the post?

– small pictures with description below , which look a bit transparent too
– when you move cursor on the picture in highlights( like on picture season 5 episode 3)

– is it some sort of video gallery plugin used ? Do you know which ?

So the question is what plugins should i get to achieve similar results?
If you know the name of the plugins , whether they are paid or not ,please let me know .
If plugin is paid , do you know any alternative for free plugins ?
