An additional type of bifurcator is actually possible, namely one that
uses 'deflection', similarly to how light (or a comet) bends near a
gravitational object. Similarly, it would bend around pieces that it
passes. First I thought it would be a mirror of 'bouncing', but it
isn't actually. It is obvious that it differs when the first leg is
orthogonal: it bends immediately when the screen is at the side. (Note
that bifurcators can also make use of the margin as screen, when
applicable.)
