Rainbow cake: what the what.

This recipe from Whisk Kid is nothing short of highly impressive. I like the fact that the baker made this in honour of a friend who, like the cake, seems 'normal' on the outside but is crazy on the inside! Aren't we all? As a long-time fan of anything rainbow-coloured, I appreciate the effort required to execute such a recipe (i.e. loads), and it does seem worth the reward - if you have a spare couple of hours.
