and some user he says it also works on Ubuntu, but I do not know what browser it is...

regardless of whether it is on PC, smartphone, etc.
On iPhone and Mac (and Ubuntu maybe) can also restart the the machine.
The original version used a background encoded image in base64,
i have instead used a normal url to make the code easier to study.
