Ripples (New to Eye Candy 5: Nature)
Ripples lets you manipulate surfaces as if they were liquids to create waves, puddles, and radiating water drops. Ripples can also generate waveforms in psychedelic colors by selecting a reflection map. Options are provided for adjusting the ripple generator (raindrops, expand from selection, or none), number of raindrops, ripple wavelength, time, wave amplitude, wave wavelength, and refraction. Users can choose whether the effect is generated inside the selection or outside. The lighting tab gives you control over the 3D appearance of the icicles by adjusting lighting direction, highlight and shadow attributes, and reflection map.
