Prompt

create a glsl webgl shader that is setup to run in an html file. The shader needs to be like ice convering a windshield. It should start at totally clear and animate to look like ice is forming and covering the entire screen. You are the best developer I know so I expect great things! It should look realistic but it will be used to add a neat effect to a website. So keep that in mind and act accordingly.
