The world's largest kaleidoscope, located in Mt. Tremper, N.Y., is 64 ft (19.5 m) tall. There is no eyepiece people stand inside the base to view the image, which is projected downward onto three reflective panels to produce a spherical cluster of 254 hexagonal facets that appears to be 50 feet across. For Expo 2005 in Aichi, Japan, a 130-ft-high (40-m) kaleidoscope was constructed in the three-sided Earth Tower three enormous, oil-filled revolving disks filtered incoming light that was reflected by huge mirrors to produce a spherical image some 118 ft (36 m) in diameter the image was viewed by standing inside the tower.
