A fridge is never just sitting idle, what reason is there to ever turn one off instead of unplugging?

Haha, kitchen appliences that don’t have a poweroff button are actually what inspired me to draw this. It was a coffee machine in my case.

The background is made from a plain purple color with added HSV noise. Then an effect is added on top of everything by copying the entire image into a new layer and applying a convolution with a kernel like this:

-1  0  0  0  0
 0 -1  0  0  0
 0  0  1  0  0
 0  0  0  1  0
 0  0  0  0  1

In GIMP those are under “filters > noise > HSV noise” and “filters > generic > convolution”
