if you take glass and animate it you could add a water effect thats running downwards to it then use glass pains to give it a verry flat look i got the idea from thinking about iron man as i noticed in his mondern pent house he has somthing liek that with glass and water running inside it and dispite all that it looks relly flat and thin now id think possibly you may ahve to do some tweeking possibly ofcourse im not able to think proeprly atm i jsut wanted to get the core idea shared with friends on here
