Every minute, piClock scans through ribbons of digits from the number pi to find the current time and date.
26,289 digits into pi lies the block “1234”
See how many places past the decimal point a four-digit block such as “12:34
” lies, and where all the other occurrences of that block appear amid the first million decimal places.
