a slow but realistic way of creating a reflection is create a camera which moves in 8 points around the island and then export its backbuffer as a texture ... then using 8 plains setup just below the matrix which is ghosted you texture them with the camera's images from the backbuffer of it.
if you ghost that as well and turn on the ambient light, and put in a light to affect the matrix water - it does give a very nice effect
i can spend all day thinking up a million ways to achieve this ... my personal favourite would be to use a Pixel & Vertex Shader combo, cept not everyone can use them
failing that just use a sphere map on the water, gives a nice reflective look whilst not actually reflecting anything - nice, cheap and quick
