A one-handed clock on the hyperbolic plane (jpivarski.github.io)

Effing Smith chart in clocks. Will it follow me everywhere?

I don't get it. On mobile it hung, on desktop it just made a clock that had minutes no seconds, no matter my zoom level. Is this really hyperbolic or just a huge circle?

If this merely put the minutes and seconds in a readable font size along the "hour" arm, it would be cool and useful.

I could glance and see it's about 1:30 pm.

I could look for a second and see I have four minutes to my 1:30 meeting.

I could stare and get a 15-second time period.
