Find Your Name in Pi
This is a fun and clever idea: convert the decimal expansion of Pi into base 27 and name the “digits” A, B, C, D, … . This creates a way to decode numbers into words and phrases (the ‘0’ digit is interpreted to be a space, or a punctuation mark).
With this in place, you you can search for your name (or any phrase) in the infinite expansion of Pi!
This will certainly excite all those cosmological conspiracy theorists out there!
