A new Facebook video, uploaded by Hong Duong Le from Korea, shows a nail design machine in action - printing an intricate pattern on nails in a matter of seconds. 

The video shows a woman placing her finger in the machine, using a touch screen to pick a design. She then waits while something that essentially looks like a jet printer moves back and forth across her nail. Bam! In less than a minute, she's got a rad flower design - with no chance of smudging.
