This is a ridiculous presentation system that works great for creative, hurried people.

See the demo -> https://tmcw.github.io/big/demo.html (Previously: http://macwright.org/big/demo.html ) for an example of it working.

It makes text and images as big as they can be, gives you minimal styling (em) and keyboard controls for navigation.
