I had an idea to repeat same code as I saw on the internet few days ago. It looked like this: On whole screen there were numbers like 0 and 1 (binary system) and those numbers constantly changed value from 0 to 1 and reverse. It was fast but not lighting speed, the speed normal to enjoy the change. I'd like to do that also but when I try to type whole bunch of numbers on the webpage using javascript I just can't find the way. Can anyone help me with that?
