Hot off the heels from Didier’s Steamthesizer article, NHQ brings you Yoshi Akai, a consummate inventor and designer whose 19th century designs usher 20th century technology with more taste than Sriracha sauce. Whether its hacking a toy to make a synthesizer out of LEGO bricks or making notes appear out of thin air (like the wireless catcher shown above), Mr. Akai’s creations boggle the eyes and inspire the mind. Yoshi took some with me to talk about his pieces, his perspective, and the invisible.
