Artists paint light using 3D printers and twisted video walls
Who said that you had to paint light by waving an arm around? Certainly not Ekaggrat Singh Kalsi and Daniel Canogar, both of whom have created art using some decidedly unusual tech. Kalsi's project generates floating color portraits thanks to a modified 3D printer -- as you'll see in the clip below, it's akin to forming a hologram line by line. Canogar's work, meanwhile, uses twisted, mobius-like LED tiles as video walls that produce unique (and occasionally mind-bending) effects at different angles. You probably won't see these pieces in person, but they're proof that light-based art holds a lot of untapped potential.
