Erik Minnema made this really nice woodworking piece, called side by side. It’s pretty easy to build, all you need are a few pieces of wood and an inter-dimensional table saw.

Can’t get your hands on one of those? In that case you will have to resort to trickery. If it’s not photoshopped, how do you think it would be built? [via neatorama]

    In this link are some interesting observations, but not so much an explanation…

    Okay, so consider the following top view

    that is, the piece on the right has a diagonal notch
    cut in it, and the piece on the left is shorter; then
    from the correct angle, you can see through the notch
    in the piece on the right, and see the end of the piece
    on the left. It looks like you have to shave down the
    end of the piece on the right to give a clear view of
    the one on the left, hence the slight step down visible
    at the edge of the diagonal cut.

      think what we have here is a photograph of a hand resting on a photograph of two pieces of wood stacked one on top of the other. the illusion is the result of fingers of the hand appearing to be resting on a flat surface. which they are.

      the screws are a nice touch.

    I’d say it’s a combination of the theories you’ve already posted. It’s two pieces of wood screwed together side by side, the piece on the right is shorter and the end that was cutoff was screwed into the bottom of the left piece. A veneer was added to disguise the cut and the proper angle was found to make it work and the picture was taken.

    and there may not even be a veneer.. the dark lines around the second piece could be shadows from a notch being cut into the right piece. when viewed from the correct angle, it looks like it’s 90 degrees vertical when it could be a 140-160 horizontal cut.

    It is all in the funky end cut of the front piece and the camera angle…

    is it a rabet that gets gradually shallower from the back until it’s flush at the front?
