I should stop trawling the quirky Japanese websites, there’s too much temptation for buying odd novelties. Like this Mini Rubiks Cube for your mobile phone.
It’s designed to hang from your mobile phone, so instead of mindlessly sending out sms messages to people you hardly know when you’re bored, you can engage your brain a bit more creatively by trying to solve this small-size cube, which by rights should easier than the full-size one.
Available in Japan now, you can pick one up for the equivalent of a bargain £1.29.
