With 76 Synthesizer, Swedish designer Jonas Eriksson has created the sexiest iPad app interface to date. The retro synthesizer app looks so magnificently detailed and realistic, it makes it easier for people to understand how it works. The patch cords and voltage meters might look intimidating and abstruse in the real world, but they become playful and inviting when embedded in the iPad app. Not only are the chords significantly cheaper in this format, you can’t “break” them. Although 76 Synthesizer isn’t available in the App Store just yet, with this sleek design, we’re sure it will be available in the very near future. Jonas Eriksson
