Getting dirty in RGB
To zoom out (in Chrome anyway) is to Ctrl + - key. It's useful for viewing the bigger picture.
Has anyone any experience with computing RGB values for filters etc.?
(That's with JSFiddle)
EDIT: Couple of fancy ones which are nothing but pretty:
(x % 2 == 0) ? x : 255-x
(y % 2 == 0) ? y : 255-y
x * y
