Lamp for Lithophane

I have made a few of these now and think i have all the bugs worked out.  The base holds 4 lithophane prints (3mm thick frame on the lithos).  The pics need to be 4:3 to fit properly.  It is made to fit over this Lamp base:

It only costs about $10.  Put the litho prints in the base first, then put the base onto the lamp.  Next screw in your light bulb.  then put on the lid.  i use LED bulbs to keep the heat down.  you can freely spin the shade on the base to showoff whichever pic you want.  the pics can be easily changed out.
