Here’s an interesting new Mac app for you Terminal junkies looking for new shiny this morning. Cathode came out of beta a few weeks ago, and it’s an alternative Terminal app for OS X with lots of “vintage” themes to apply to the regular session window. As the name suggests, Cathode emulates those old TV screens you might have seen (and owned, too) in the 1970s and 1980s – indeed cathodic monitors.
In spite of its vintage look, the app is entirely written in modern OpenGL and Cocoa, with graphic processing done by the Mac’s GPU. The app, in fact, uses a lot of animations to replicate the behavior of old televisions with flickering fonts, interlacing, curvatures and flashes. It really resembles the old monitor your grandparents might still be using today. You can choose between different themes and adjust fonts and colors, enter fullscreen mode and set the curvature of the screen to your liking.
The licensing method is clever as well: you can use the app for free, but the picture quality will slowly degrade until Cathode is relaunched. If you purchase a license ($20), you can customize the interface and avoid picture degradation.
