  Magnetic skyrmions are nano-scale spin textures whose stability, size and
ease of manipulation make them strong contenders for next generation data and
logic applications. Here we illustrate fine motion control of skyrmions, we
show how they can be moved in any direction and for any distance, in the plane.
We demonstrate, using simulations, two novel skyrmionic devices whose function
is predicated upon the fine planar motion control of skyrmions. The first
device is a field configurable logic gate that could be used as a component in
a larger skyrmionic processor. The second is a field configurable skyrmion
spiking neuron device that could be a component in larger skyrmionic neural
networks. Such devices are highly energy efficient and are potentially useful
in the field of neuromorphic computing, which seeks to build 'brainlike'
computers. Finally we explore the concept that this free planar motion, which
enables us to ignore the skyrmion Hall effect, offers an important new paradigm
in skyrmionic device theory moving away from the current applications such as
racetrack memory.
