Yes that is a cake!I've always loved the Art and Craft Exhibitions of shows. Full of great works of talent.
The Melbourne one is nowhere has huge as the Sydney Royal Easter Show, I like it that better. Less crowded and you actually get to see it all without some obnoxious person shoving you out of the way or having to watch their child put their sticky fingers and what ever they are shoveling down their throught all over the windows.
I like the works of brilliance that are done by people as young as around 9 and as old as your grandma.
