Here's a video that makes the performer seem like he can think of two things at once! This is Rubik's Cube Champion Shotaro Makisumi, also known as “Macky”. In this video, he's juggling two Rubik's Cubes with one hand, while solving a scrambled Rubik's Cube in his other hand!

You may recognize him from his blindfolded Rubik's Cube video (also linked to in this post).
