Dresden Glass Bead Star: concentric designs of spherical glass beads produce geometric symmetries of shadow and refracted light from a tea light candle which serves as a point source of illumination. This “Glasperlen Stern” candle holder is one of many configurations offered from Dresden artist Andreas Schildhauer, each with glass set into porcelain from Freiberg. ➡ Follow the link in my profile for info on where to get these projection candles and other amazing items featured here on @physicsfu
