The "Evolution of Type" goes mechanical. This time, instead of performing letter surgery, I simulate the heartbeat of a letter. Exhibit "A Pulse" consists of a plywood case, an electric motor powered by a rechargeable 12 V battery, some gears and an overall latex cover. The tricky part was the precise installment of the push rod. No need to do do this but I just had to paint the heart in red. See the project in my Behance portfolio.
