Mark's awesome business card from TestBash / MoTaCon 2025

Got this businesscard from Mark Benson at TestBash, truly living up to his Creative Technologist label. Complete with five test cases to figure out and a hidden easter egg that can only found after getting all five working. Took my a while after getting home to get around to figuring it out - but an awesome challenge to go back to basics and figure everything out from just a few lights blinking or burning to give you feedback. (And of course an awesome feeling seeing all five light up green!)
