The roller might be one of the most efficient ways to apply paint to walls so perhaps it also works as a gadget screen cleaner too. The iKoroKoro (from Japan if you couldn’t figure it out from the name) cleans fingerprints and smudges off your touchscreen devices by just rolling over it. Is it better than just using a cloth? Who knows, but it’s certainly looks like more work and more fun. I guess that’s just how they “roll” in Japan. (via akihabara)
