51 inch diameter cylinder resting on top of a 60 inch tall plexiglas 'silo'. Light source: slide projector 30' up. Darkened room. Water depth ranged from 0.5 cm to 1.5 cm to 5.5 cm (a few may be deeper). Canon EOS 10D images at 1/60 sec. The shallower depths produce solitons/ripple-bores (as in 2d and 3d images). The rather fleshy large-amplitude waves are in the deeper water. The vortex image should be improved, also there are no images of the great concentric rings that occur when the cylinder walls are thumped.
