This applet is simulation of  raindrop on the  image.
I checked this how it works on the net, and I found that it is too slow to start.
One reason is that "Bekkoame" server is too slow to response.
Another reason is that I used too large lookup table to make calculation fast .
I am afraid that user may think their machine freezed.
So if you want to observe this applet , please download my class file and run it locally.
Location of this applet's class files is

INTERVAL is interval time of raindrop.
RATIO is amplitude of wave.
DECL is deceleration rate of wave amplitude,(*0.01), must be smaller than 100.
