:jumpclap Cool pattern Rod ...never had a flannel pattern before to play with

but something weird happened with your pattern, each time i open that pattern of your with xnview it changes,
sometimes are the colours to change sometimes the shapes sometimes both

Almost if somebody was swapping the colours channels ...









and then become darker



sometimes instead the change seem to be from positive to negative



i prefer the negative (i believe the "positive" become greenish because some swapping incident , negative restored colours more close to the original...

oh what happened to the negative ,now...now it seems not only a negative but also processed with fractalius



The more i look the pattern the more its geometric become unstable... as if reflected in some sort of distorting mirrors







and go on on shifting...





I start to be worried if all this happens only by opening the file with Xnview , then what may happen opening with gimp , gmic or mathmap ?

anyway sharing patterns may be a good idea :
you share 1 and you got 15...no bad
