This is a cake. I'm amazed at the skill but still asking... Why?

But how could you eat such art?

I'd take a picture and then eat it because I don't believe in wasting food

I'm with you frisky, also it just looks so delicious

How much of this is cake, though? A lot of it seems it would be sugar paste or sugar glass. It seems more like a confectionery sculpture, than anything. Where did you find this?
