This is by far the most popular comic on my site. It has reached close to 220,000 notes on Tumblr and appeared across Reddit,9gag and Imgur a lot over the last few months . I’ve had a lot of people asking for it as a print and for permission to use in various ways. The only problem was that there had been a mistake with the colours of the squares in one or two of the panels leaving the cube itself unsolvable. I decided to fix it for anyone out there who intends to use it in the future.
