The skin-ablation laser tattoo we showed you recently was creepy mainly because burning your naked skin is going to hurt, but this new laser body-mod tackles a safer target, fingernails. The portraits of famous bods you can see in the image are laser-etched into black nail polish (I know, it looks like they’re made of seared, blackened nail, but they’re not), and member lamedust over at Instructables has got a pretty comprehensive guide. So if you’re crazy, you too can etch pics onto the end of your digits. The video makes for interesting watching.
Scientists in the UK have thought differently about touchpad designs: their system peeks at your fingertips to see what you’re touching. It can sense when you’re pushing on something and how hard, so everything —even a 3D uneven surface— could be made into a touchpad. Quite why they chose to demo this with a purring rock we’re not sure. But we like it.
