That's quite nice indeed. Would be really cool to get the whole screen filtered and maybe even a menu to tinker with the settings (like you get with SWTG, GA ...).
A downloadable novelty for Windows
SuperCRT is a small Windows app that samples a 256x224 region of the screen and draws it to another window using the CRT simulation from Super Win the Game.
Hit Esc while focused on the sim window to customize the CRT settings.
Curious how it works? Check out this blog I wrote for Gamasutra: http://www.gamasutra.com/blogs/KylePittman/20150420/241442/CRT_Simulation_in_Super_Win_the_Game.php
