I’m a bit lost on the what’s the point aspect too.
That question could be aimed at absolutely any art whatsoever. It could be aimed at stunning photographs, multi-million pound renaissance classics, nice looking cars, fit girls, funny looking buildings… what’s the point?
This is just one area of art that is achieving impressively high levels of skill which is being celebrated there. It’s very, very good technical work that can make people go ‘wow!’ and making people stop, stare, think and discuss… well that’s what art is isn’t it?
You don’t have to like it but it’s hard to question the objective.
