Requested Dark Side of the Moon by Pink Floyd. I kept the clock as basic as possible. No seconds and the triangle remains as was. The entering beam shows the minutes, the rainbow the hours. Just the entering beam and the returning rainbow. During the day, only the angles change, but the basic principle does not. Every look at it offers a different composition, a variation on the theme. It just shows the power and the serenity of the original artwork by George Hardie.
