For me, believable art & design comes from good observation. While developing my new identity for Boodoo, I wanted to create an etheral, theatrical effect by simple means. I created this letter B with 3D effect in Adobe Illustrator from a standard font (Gotham), and by observing how light & shadow behaves as it is cast on an object. No 3D rendering involved. This image courstesy of Wikipedia shows the shadows of three light sources: Red, Green and Blue.
