An interview with 280 North on Objective-J and Cappuccino. Fantastic comment thread with involvement from the guys who created Objective-J. Just like Objective-C, Objective-J is a preprocessor that runs against regular JavaScript source files so you can use JavaScript and Objective-J idioms interchangeably. 7th June 2008, 7:40 pm

280slides and Objective-J. 280 slides uses an Objective-C clone written in 13KB of JavaScript. I have to admit I’m completely baffled as to why you would want to use Objective C instead of JavaScript, but evidently it worked fantastically well for them. 7th June 2008, 4:09 pm

Programming Nu (via) Interesting new programming language—Lisp style syntax, Ruby style semantics, built in Objective C bridge so you can access Cocoa APIs directly. 1st October 2007, 9:49 pm
