Proof of Work [random]. This piece is composed of cards with random numbers stamped on them. Daily for one month Zea invested some of his productive time by throwing dices following a simple algorithm. First, throw a 20 sided dice, that would indicate the total of random numbers lines to produce that day; then for the number of times determined by the first throw, roll a group of different sided dices to generate the indicated amount of line digits. The outcome of the process is a card that exhibits the artist’s proof of work on that specific day.
