The Galaxy from TokyoFlash shows hours on the big pips, the red pips show five minute intervals, and the green pips show single minutes. While it’s not immediately intuitive, it’s a bit better than TokyoFlash’s traditional “the green blob shows the hours since your last bowel movement, the red blob shows milliseconds elapsed since 1929, and the blue blob is there to tell you that we care” styling.
The Galaxy costs $132 and is available online. Pick it up and look like a star captain in your spare time.
I think these gadgets are intended more for giving your brain a workout trying to tell what time it is then actually providing the time.
