As great-looking tattoos go, this is right up there.
O'Rourke told the Huffington Post the tattoo took two and a half hours to complete.
He revealed:
I love geometrical tattoos, so this one was a lot of fun and a challenge at the same time.
I've had a lot of interest from this tattoo and people have received it really well.
I've gotten a few more requests for this kind of work in the coming weeks, which is great.
BuzzFeed has contacted Buckley to get some more information on his new inking.
