  Vortices are whirling disturbances commonly found in nature ranging from
tremendously small scales in Bose-Einstein condensates to cosmologically
colossal scales in spiral galaxies. An optical vortex, generally associated
with a spiral phase, can carry orbital angular momentum (OAM). The optical OAM
can either be in the longitudinal direction if the spiral phase twists in the
spatial domain or in the transverse direction if the phase rotates in the
spatiotemporal domain. In this article, we demonstrate the intersection of
spatiotemporal vortices and spatial vortices in a wave packet. As a result of
this intersection, the wave packet hosts a tilted OAM that provides an
additional degree of freedom to the applications that harness the OAM of
photons.
