What is it?
These sixteen lights show a binary number, increasing twice a second. When it fills up all the lights, about every 9 hours, 6 minutes, and 8 seconds, it resets and the colors change.
I think of these “bit counters” as a timepiece designed by computers, where we humans have to adapt to the most convenient representation of a number for a computer, rather than the other way around.
The addition of a few extra lights makes a big difference in how long it takes to fill up.
|Number of lights (bits)||Number of ticks||Amount of time, at two ticks/second|
|8||256||2 minutes, 8 seconds|
|16||65536||9 hours, 6 minutes, 8 seconds|
|24||16777216||13 weeks, 6 days, 2 hours, 10 minutes, 7 seconds|
|32||4294967296||68 years, 2 weeks, 5 days, 3 hours, 14 minutes, 6 seconds|
