Now this is one device that is set to frustrate you – the Rubik’s Mirror Blocks Cube. As though the original isn’t already confusing enough (long time readers will know that I have yet to solve the darn puzzle and steadfastly refuse to look to the Internet for a solution), this $19.99 model is more than enough to drive any sane person to the nearest sanitarium. If only it came packaged with a hammer – the mirrored surface ought to do its part to irritate you further by reflecting your frustrated face while you have a go at it.
