With modern liquid crystal devices it is possible to implement digital holograms for the modulation in amplitude and phase of light: so called 'structured light'. In this non-specialist talk, we will introduce the concept of complex amplitude modulation, and show how light can be tailored to have interesting properties: defying diffraction, twisted like a spring in intensity and phase, and made to bend around corners! The ability to create arbitrarily complex fields opens up a plethora of applications, from controlling the micro-world through optical traps, to probing the quantum world with twisted light.
