START - Start counting
STOP - Stop counting
ZERO - Reset the counters to 0
SPACE - Right arrow to step count one by one
Use "Turbo Mode" to count faster (SHIFT + FLAG)
Experiment: Switch to Turbo Mode then measure how long the binary counter takes to reach one million (in decimal). Then, post your time (and browser) in the comments. On my device, it takes 23 s (Firefox), 9.5 s (Safari & Chrome). Using Firefox, to get to one billion, it would take about 6 hours, 38 minutes. It would take about 276 days, 9 hours to count to one trillion. And, it would take 757 years, 83 days, 21 hours to count to one quadrillion.
