The best kind of script

Instant: coffeescript on the go

Thursday, April 29, 2010

Life’s too short to not write coffeescript on the train. So I made a HTML5 offline web app for your iPhone that lets you (try to) do just that. Head over and add Instant to your iPhone home screen, then click on the “Run” button to see the example coffeescript go.

Parcycle: A Particle System with HTML5 canvas

Thursday, December 3, 2009

All this PPK “iPhone developers are stupid” awesomeness got me thinking. Now, if there’s one guy I’ve got respect for, it’s PPK.

Tuesday, August 18, 2009

Conway’s Game of Life is a simple cellular automaton based on a few simple rules. There’s about fifty gabillion implementations of it around.
