FreeAp f is a Comonad

While thinking about comonads as spaces and Day convolution, I realized an interesting thing. The free applicative functor generated by a comonad f is also a comonad.

The free applicative can be defined in a few different ways, but I like to define it like this:

data FreeApplicative f a = Pure a | Free (Day f (FreeApplicative f) a)

Porting Prezi to Elm in 99 lines of code

Elm is a statically-typed functional programming language. Its compiler produces safe JavaScript which is guaranteed to be free of runtime exceptions. Moreover Elm is packed with a bunch of powerful abstractions which let us build visual and reactive Web applications in a few lines of code.

As an example, I show the implementation of a simple framework for building Prezi-like presentations. It's just 99 lines of code!
