I think the effects can work clientside, I'm not sure. It's a good idea though.
Had to read this over a few times. Might be better if you checked your grammar and spelling a bit.I'm not sure how it could be coded so onto certain people can see the effects and if you can switch it on and off. I'm the type of person who uses default shaders and textures on minecraft, so...Might be an okay idea. I'm not a fan of lens flares and bloom and such, but maybe some people are.
I think by sick he means awesome. Not ill. As for what you asked, did you find out if these were clientside or not? I have a feeling they are.
