Liquid water is more random than ice. But there are still patterns to it: currents, tides, etc. And sometimes you get whirlpools. These are -- to modern science -- fairly predictable. A thousand years ago (or 10 thousand, pick whatever number makes you happy) the working of the tides seemed too ordered to not have a cause, but they couldn't discern a cause, so it must be a god doing it.
And that's the real problem with ID. To an ID proponent, anything that "seems too ordered, it didn't happen by chance," is taken as evidence of a design; and by extension, a designer. To a scientist, anything that "seems too ordered, it didn't happen by chance," is taken as a good thesis topic.
