I woke up to these patterns of sunlight projected onto my curtain ... and then wondered how I could replicate them in Adobe Illustrator. Learning a new skill heightens my awareness of things around me. It's possible that learning German may be my next self-education project since I find myself wondering what curtain would be in German. Light is das Licht and curtain is die Gardine or der Vorhang. I looked curtain up just for you (and me).
