Inexpensive DIY light box - Laptop style for storyboards and animation

Here is a simple homemade light box made form a 11 x 14 clear plastic picture frame.
Cut a pair of sides to fit from 3/4 plywood and paint them white. You will need a bottom cut to fit from hardboard also painted white.  A small  lamp available in home stores is useful to move around under your drawing or expanded to two lamps  fixed to the sides for a more permanent job.
