This is a doozy. Stay with me for a moment. The client wanted a very simple, direct way of saying that her software does numbers for construction companies, especially tradesmen and subcontractors. In a device. Well, she got it. The logotype characters spell “tact,” which is how they answer the phone, the circle and line-segment art above the name conveys the themes of construction, especially trade work, and, when turned 90º right, the marks spell out T A C T in morse code.
