Delicate markings have continued to emerge over the past few months. Be it chaotic scratch or precise design, artists are predictably pushing boundaries and reinventing the creative wheel.  Ritwik Dey, an Interactive Designer and data visualization specialist at R/GA, demonstrates this brilliantly with his Harmonogram series of Lissajous figures.  Using only a flashlight-pendulum set into motion, a piece of cardboard with a pinhole for light and a camera set to expose between 30 and 90 second snaps, Dey has created his own light version of the hypotrochoid art set.  These metallic wonders quite acurrately represent why Dey works as an information designer.  Check out his weekly photo project to stay abreast of his latest musings and don’t forget to vote on what you’d like to see next!
