A dot for every second in the day
 Getting a feel for big numbers Lots of dots A dot for each day

 You can use Lots of dots to get a feel for time. At one dot per second, here is what a day looks like... Run it as a clock!(Any problems? Please let me know.)

One Day where each dot is one second.
 00:00 to 02:47 - 05:33 - 07:10 - 11:06 - 13:53 (1:53 pm) - 16:40 (4:40 pm) - 19:27 (7:27 pm) - 22:13 (10:13 pm) - 24:00 (midnight)
 early daytime late

 one second
 ten seconds
 hundred seconds (10 x 10 = 100) about a minute and a half
 minute (60 seconds; 6 x 10) 5 minutes (300 seconds; 3 x 100) 10 minutes (600 seconds; 6 x 100) 15 minutes (900 seconds; 9 x 100)
 thousand seconds (10 x 10 x 10 = 10 x 100 = 1000) about 15 minutes

hour
3600 seconds (60 seconds per minute x 60 minutes)
3 x 1000 plus 6 x 100
 6 x 6 = 36
ten thousand seconds
almost 3 hours (2 and 3/4 hours)
102 x 102 = 104 (10000 ; ten thousand )

500 minutes (30 thousand seconds; 3 x 104 s; ~8 hrs)

~1500 minutes == 1 day (1440 min; i.e. a -4% error)

```Notes:
The clock needs to "phone home" every few minutes to get a new layout
with the active zone moved.  Sorry.  Please let me know if this is an issue.
Sometimes there is a gap which isn't colored in for some minutes.
Why is the bottom-right corner of the box not filled in?
Because there are only 60 x 60 x 24 = 86400 seconds in a day,
but the big box is        300 x 300 = 90000 dots.
So 3600 are blank.(4%)
Thanks to a reader for the question.

```Doables:
I'm not sure this background is the right thing. [Removed]
`YEAR Mon SECOND' and `Year SECOND' counters.
% of day.  Place 86400 near second counter.
Being able to toggle the color would be neat (black is sleep,
green is practicing guitar, etc).  But rather more complex to program.
Perhaps an ephemeral toggle on whether to color?
For browsers that support div, could add time-of-day overlay.
And event markers.
A year-line, dot per day. (uncomfortably long?)  Since 1950 stack.
Reverse?  Fill up with experience, rather than drain opportunity. :)
