In my continuing saga to bring old-school displays to new-school (word?) devices, I’ve created a “bulb view” that displays characters in a grid of “lights”. The best way to describe it is probably just to see it:
Like previous LCD view you can set the colors for the lit & dim bulbs, but improved from the LCD view, you can use letters, numbers, and most punctuation/special characters. Again the rendering is done in pure Quartz2D.
The source, including demo apps for both the Mac and iPhone, can be found here. With this view I was smart and made it conditionally compile various parts so that it can be used on either the iPhone or the Mac, without needing separate files.
