The CRT effect is immediately what stood out to me as well. It's the first time I've ever looked at a "CRT filter" that really gave my eyes the sensation of looking at a real CRT, specifically Amiga. It's so good that I would compel the author to share it with Amiga emulator developers to see if there's any chance of it being implemented. Maybe except for the line that occasionally travels from bottom to top, that's more reminiscent to me of a camera artifact and not something I experience with my eyes on Amiga monitors.
Agreed about the moving line, also the effect is a bit overblown IMO. And, the scan lines should bend along at the top and bottom. They shouldn't be straight as they are now. Very good approximation though.
Also, HUGE reflections are missing from the 1084 :P (I had the 1081 myself which was kinda the same but with mono audio).
