It's funny. I've been programming Cocoa on and off for two or three years, and quite intensively over the past five months, but never really did anything requiring lots of drawing. I've been putting it off...
Which is odd because normally the first thing I do in a new programming language is draw Mandelbrot figures. Well, I'm writing some software to plot surfaces, so for test cases I've been using data representing areas of the Mandelbrot figure: Fractals are fun!
I must say I am increasingly concerned about the amount of stuff that gets put in the trash can without any thought for the environment. I have decided to write a new "green" trash can application which filters any open source code, data or applications and recycles it by compressing it and making it available to the rest of the open source development world via the web. To prevent the trash can recycling itself, I will of course have to make it a proprietary, closed source application.
On a separate note: I discovered today that Schostakovich's piano concertos make the perfect antidote to an afternoon of Bach's violin partitas.
