By the power of substitution; I change you!Benefit - no updatecycle-lag that you get with a more 'sofisticated' method. You know the one that Alex would use.
Downside - My head feels funny.
Couldn't get quaternary or quinary to work. They are impossible with the substitution method.
And I didn't want a unary numeral system based clock. 59 signs just to write you 59? No thank you.
But aside from those three, it's the most widely used numerial systems. :D
Also - Thanks Captain_Mayhem, you how though of a hexadecimal clock and truly the father of this idea.
Beats watching twilight...
