ABSTRACT:
An apparatus for creating a water disk effect without water. The apparatus includes first and second disks, each having a first side with a substantially planar surface and a second side with a surface textured with a three dimensional (3D) pattern or topography including raised, arcuate ridges in a whirlpool or spiral arrangement. The apparatus includes a housing that supports the first and second disks for independent rotation about a common axis. The disks are positioned such that the first sides are proximate but spaced apart to avoid contact, such that the 3D patterns face outward toward viewers of the apparatus. The apparatus includes a drive assembly rotating the first disk in a first direction and concurrently rotating the second disk in a second direction opposite the first direction. A water disk effect is created during counter rotation when light from the Sun or other source strikes the disks.
