[SPACE] to generate a random PIN code. I wanted to have a way to randomize personal ID codes, so I turned to Scratch and made this in, like, 10 minutes. There are no sprites, but there are over 3.65 QUADRILLION possible codes.
According to my (possibly inaccurate) calculations, it would take about 1220.37 years to run through all the codes. To hit this number, I used the 'Input Count per Second' I made. My IC/sec clocked in at ~95,000/sec My calculations (3,656,158,440,062,976 / 95,000) / 31,536,000 = ~1220.37
