Question about security web check

Hello.

I did mistake and I visited this website: http://www.takethislollipop.com
I don't know if there are some dangerous or if I downloaded some virus to my pc or to my opera browser. Please, can you check this website? Is it clear? Or could they stole my passwords or something? I only visited it, I didn't write any email, password or something else.
Can you help me please? 

Thank you very much!
