Thanks
... yeah it's nice, and there is a separate shader that does phosphor decay simluation, kind of.. but only at 50Hz so it's not very precise, I uploaded a new remake just now where it is actually useful, when the bob-vector move fast, the decay shader makes it look a bit smoother.
trivia: I did have an 8-pass shader for a while, with more bloom, but I reverted back to this, just the decay shader + crt-shader, since the other one was a bit heavy..
