That view is of the business end of the heart of a 3LCD projector.
The corner of one of the LCDs is visible with the orange ribbon connector coming out the top.
Here is the full size photo.



glatt came close with the CCD and the diagonal seam.
It's actually two prisms joined to make a cube.
The color blotches are from the glue/epoxy used to attach the mount to the cube.
The angle of the shot accentuates that, but it does not interfere with the function.
Here are some shots of the stripped down cube.
It also has a di-chroic coating which makes for a really eye-catching bauble to put in a sunny window.









These shots are of the same cube at different angles.
In the second shot you can see a double reflection of my camera lens.

The company I work for installs and services audio/video equipment, and I took apart a dead projector to remove the circuit boards which are considered hazardous waste and can't be thrown in the trash.

There were also lots of lens, mirrors, and pieces of filtered/polarized glass in the "light tunnel assembly" as it's called.
A lamp sends light through the tunnel and probably a dozen lens/mirrors/filters before it is sent through the LCDs which actually form the image.
The image then comes out the open face of the cube before going through the focusing lens which projects it onto a screen/wall.
