Create the servo mechanism for the eyes. Bend a paperclip so that it goes through the servo arm (and still rotates easily). Next, poke a hole in through the foamcore (the part with the eyes) using the paperclip and secure it by bending it down. Make sure no sharp parts are sticking up.

Test out the mechanism. When the motion trigger in activated, the eyes should move from the normal set to the scary set. Position the servo arm at the base of the foamcore platform and test out to make sure that the eyes line up with the portrait in both positions. Once you are happy with the placement, trace the base of the servo.

Cut out where you just traced with an X-acto knife (you may want to make the cutout slightly bigger than the tracing). Then cut two pieces of ¼" thick basswood to mount the servo to. Flank the sides of the hole you just cut with the two pieces of basswood. Secure them with small screws from the backside of the panel. Place the bottom of the servo through the hole and secure it down to the two wood pieces with small screws.

Last step is to add a foamcore cutout over part of the eye mechanism to hold it in place when it sits in a vertical position. See the attached template file for dimensions. Then tape the foamcore cutout between the wood dowels that flank the eyes.

Power up, secure the back panel to the frame, and hang on the wall. When somebody walks by, the eyes will go from normal to very very evil. Spook your friends!!!
