In a call to artists, the Renaissance Phoenix Downtown Hotel chose local muralist Clyde to give the building’s west exterior wall (along Central Avenue) a makeover in his signature 3D, storytelling style. At first glance, the 144-foot mural, titled “Timeless,” will captivate you. On second and third glance, however, you might see it a little differently. That’s due to the ever-changing shadows cast from the overhanging shade structure. Each hour of the day, the mural changes as the sun moves across the sky. During the last few hours of sunlight, you can catch it shining directly onto the glass prism, held by the person in the painting, and the key inside comes to life with an indisputable glow.
