Faux Stained Glass Panel

I would like to have a large stained glass panel to install in the door of my greenhouse, but it would be much too expensive, too heavy, and would require serious bracing. So, I wonder if people make faux stained glass panels out of transparent, colored, plastic sheets. Not the static cling type, or the "wall paper" type...something that can be made to realistically mimic a stained glass panel. If so, I would really like to find out where to get good supplies to make one myself. Can anyone help?
